Lucas Philip "Luke" Dunphy is Claire and Phil Dunphy's third and youngest child, and is the young brother of Haley and Alex Dunphy.


Luke was born in California, USA on November 28, 1999 and was conceived by Phil Dunphy and Claire Pritchett as their third and youngest child. Luke, along with his step-uncle Manny, attened Walgrove Elementary School and then they both attended Palisades High School.


Luke is a rambunctious, playful, mischievous, and immature teenage boy who is often doing his own thing. He is also known for being a boy with low intelligence, which has supposedly inherited from his father, who is not so many smart either. This makes him to be very innocent and not always understand the repercussions of his actions, which is clearly shown in "Coal Digger", when he announces at a family gathering that his mother thought Gloria was a "Coal Digger". He is also thought to be a bit vacuous, because of many questionable actions, such as getting his head stuck in the banister and jumping on the trampoline wearing only underwear and a box on his head. Like his father, he is believed to have ADHD, as he repeatedly becomes distracted when he has to do something important. He is easily annoyed when people show intelligence: Whenever Manny says something with long words, he says 'You're making it lame again!'.

Luke has a special relationship with his father. They have more a friendly relationship than a family one, as Phil is mostly calling his son "buddy". They almost have the same likes and dislikes and are most of the time seen doing something together, such as playing video games, watching TV, living adventures, do sports, and others. However, they don't have exactly the same likes/dislikes, as in some episodes it has been shown that they share different ones:

  • In "Fizbo", it is revealed that Phil is afraid of clowns, while Luke likes them.
  • In "The Butler's Escape", Luke wants to quit magic but Phil can't accept it because Phil loves magic.
  • In "And One to Grow On", Phil wants to set Luke on a dance class, which he dislikes, because Phil says that he comes from a long line of dancing Dunphys.
  • Luke loves a lot his father and vice versa, as in many episodes it has been shown his family love towards him:
  • In "Phil on Wire", even though Phil is afraid of walking across a tight rope, Luke encourages him and he finally does it.
  • In "The Old Man & the Tree", when Phil attempts to meet his goal of traveling the length of home to Canada on a stair master, Luke first thinks that it's not a good idea, but later, he encourages his father to do it.



Unlike with Phil, Luke has a more familial relationship with his mother. He usually asks her help for something important, mostly for a school problem: homework, exams, projects, etc. While with Phil, for something about girls or for have fun with him. Also, when Luke does anything that makes Claire upset she gets mad at him, while Phil tries to bond with him and to not get mad at him. Despite this, Luke has demonstrated that he loves his mother in some episodes:

  • In "Manny Get Your Gun", when Claire thinks that Luke prefers his father before her, as he wanted to go with Phil to the restaurant for Manny's birthday instead of her, Luke reassures Claire that she is actually fun to make her feel better.
  • In "Snip", Luke first gets mad at Claire for embarrassing him at school, but later he realizes that he has been hard on her and gives her a rose to apologize.
  • In "The Last Walt" Claire comforts Luke after he opens up about how he feels about Walt dying, before this happens Claire thought that Luke showed no emotions because he isn't dealing with it.

Haley and Alex

Haley and Luke are happy
Haley and Alex are Luke's older sisters, Haley and Luke don't have as many fights as she does with her own sister, in fact Luke rearely ever fights with his sisters although they do call him names sometimes.
  • In "Truth Be Told", Alex and Haley have a little fun, and convince Luke that he was adopted by teasing him into thinking that Phil's old girlfriend Denise wanted to take him home. Meanwhile Luke is terrified it's a ruse that causes him to flee the room several times once Denise arrives. 
  • In "Me? Jealous?", while Haley and Alex are fighting, Luke interferes to make them stop and tells them that they are both bad big sisters to him. Luke's words make Alex and Haley to remember their old habits when they were younger and they were dressing up Luke, something that Luke is not happy about.
  • In "Come Fly with Me" we see Haley and Luke playing a handclapping and singing game, Gloria says that it's a bad sign that a bird smashed into a window in the Pritchett house and we come back to Luke and Haley who begin fighting immediately after Gloria says this.
  • In "Baby on Board", Luke reluctantly gives Haley her college acceptance letter and realizes that Luke was hiding it because he's gonna miss her (although Luke denied it). And sure enough, in "Schooled", when Haley is going to college, Luke is so sad about it and to tell her goodbye he puts on a mask so she won't see that he is crying inside, to which Alex makes a comment that Luke is 'literally masking his emotions' demonstrating that he really loves his sister.
  • In "The Long Honeymoon" we see that Haley and Luke seem to get along really really well when Alex isn't around, they seem to be perfect children, the entire family seems to fit very perfectly together when Alex is building houses for the homeless, when Alex comes back we see that Haley and Luke immediately start to fight and Phil, Claire, Luke and Haley starts to feel stressed out again, but this only starts to happen when Alex comes back with a lot of stress on her mind. Phil and Claire then deny that Alex is the problem in the household. But it is quite evident that Alex seems to be the problem as when Alex leaves the house for a minute, Haley and Luke start being a happy family again and this is evidently broken when Alex comes back in the house.
  • In "The Big Guns", Alex gives Luke advice to ignore their next-door neighbor Tammy LaFontaine when he passes her so then she'll notice him and want him to kiss her because Luke developed a crush on Tammy.
  • In "Closets, Closets, Closets, Closets", Alex tearfully tells Luke that she and Sanjay broke up. Instead of going back to the girl he and Manny were with, he decides to stay and comfort her.



Manny is Luke's step-uncle. They are good friends as much as they are family and get along quite well, although Luke is often annoyed by Manny's opinions, as he is so much more mature than Luke. However, Luke appears to be more popular at school than him, and usually helps him to be more popular or score with a girl.

  • "Coal Digger" marks the first interaction between the two, when they get into a fight at school, because Manny refers to Luke as "his nephew" which he dislikes.
  • In "Virgin Territory", Luke helps him with a girl named Miranda by taking Cam's car and driving it down the block of her house to impress her.
  • In "Mistery Date", Luke helps Manny to find a girl Manny likes, attending the 3 bar mitzvahs where she is.
  • In "A Hard Jay's Night", Luke goes to a party against Manny's advices. Manny follows him and when they reach the door, the party host recognizes Manny but not Luke, revealing that Manny had been invited to the party making Luke feel rejected and dejected, as he always thought that he is the cool one and Manny the awkward one. But Manny comforts him saying that if wants to keep being cool, he has to change his style like him.


Luke was often seen to be jealous of all the attention Lily received for being the 'cute' one in the family instead of him. He and Manny used cookies that Claire made to try and lure Lily into a trap so she would spill the milk and get in trouble but Cam ended up being tricked instead. He liked to insult Lily for example he told Mitchell that Lily had no emotion in her eyes.

The same thing happened after Joe was born, Lily became worried that he was the cute one and she was being replaced and Luke told her that they 'would talk'.

Love Interests


In "New Year's Eve", Luke invites Becca along with her cousin Joyce to the Dunphy house. Luke plans to make out with her in his room, but Haley and Alex try to interrupt them several times, being the new adults around the house, until they just go in with laundry and Haley trying to be her Mother, tells Becca to leave, threatening to call her parents.


Simone is a girl that Luke has a date with in "Best Men".


Carly is a girl that Luke has a crush on in "Suddenly, Last Summer".


In "A Fair to Remember", Luke has a crush on Sienna, a girl from his school who is also a good friend of Alex's.


In "Spring-a-Ding-Fling", Luke has a date with Rhonda for the spring dance in his High School. Claire wants to help him to score with her, so she helps Rhonda to dress more like a girl and be beautiful, as she always wears very dirty and manly clothes. Luke is not really happy with that because he preferred her the way she was and asks Claire to "fix" her. However, the two are later seen dancing together, so he may really like the new Rhonda.


Tammy is the daughter of Ronnie and Amber LaFontaine, the Dunphy's next-door neighbors.

In "The Big Guns", Luke develops a crush on Tammy, watching her sunbathe on her parents boat, from his bedroom window. He tries to talk to her, while she blows him off and insults him. Alex gives Luke advice to just ignore Tammy when they see each other, which he does — which in turn bothers Tammy enough that she wants him to come back and talk to her.



Manny is the son of Gloria Pritchett, who is Luke's Step Grandmother which makes Manny his Uncle, Luke and Manny have a great friendship as much as a family relationship:

In "Coal Digger" Luke and Manny are in trouble for fighting in school, Manny calls him his nephew and Luke doesn't like this, Luke just hasn't gotten used to him being his Step Uncle. "Coal Digger" also marks the first interaction of any kind between these two characters, we see by the end of the episode, Luke and Manny have made up over playing games and talking about their issues.


Walt Kleezak was the elderly neighbor of the Dunphys', Walt needed oxygen tanks to breathe, which Luke subsequently finds cool, it's revealed that Walt had fought in the war and had a love of playing video games with Luke:

In "Boys' Night" Walt makes his first appearance, Claire and Phil tell Luke not to play with him as they seem to find him creepy and think he isn't a nice person. When the Dunphy family are playing sports in their backyard, Claire bats the ball into Walts' backyard and they finish the game as Phil and Claire are afraid of going to his house to ask for it back nonetheless Luke ignores his parents and curiousity gets the better of him, as he goes around Walts' house and is the only member of his family to risk getting the ball back, Luke asks questions to Walt, at first Walt isn't very keen on Luke and doesn't trust him. Luke annoys Walt so much that he gives up and tels Luke to get his ball. Later on we see Luke come back home and tell his parents that he hung out with Mr. Kleezak in his house and Claire seems disappointed thinking that he is a creepy old man, but Luke tells them differently, as he has actually seen his persoanlity and not judged it. Claire tells Luke that he can't go back to Walts' house because he's weird. Luke then tells his parents that it's unfair and they don't know him as they're too afraid to talk to him. Claire and Phil then go over to tell him they are concerned about his friendship with their son, Walt gets offended that they think he is a pervert and he makes them leave his house. In the end, Walt stops by the Dunphy house and gives them Onions from his garden, he then tells them he used to be a fireman and he doesn't hurt kids. Feeling bad Claire and Phil invite him in but he doesn't come in. Seeing that Luke may be right and he is a kind, friendly old man and they judged him too quickly they accept him being a family friend.

In "Lifetime Supply" Luke asks Claire if he can invite Walt over, Claire asks Luke if he thinks it's weird to have an 85 year old best friend, Luke thinks it's cool that he's older than him and has been in the war. We later see Luke and Walt playing games on the Dunphys' couch, Phil is there with them, but it's only because of the news he thought he was going to receive and not because of supervising. When Luke takes a break for the toilet, Phil bonds with Walt over new he thinks is true: he is going to die, although Walt reassures him that the doctors told him he'd been dead 10 years ago and he is still alive.

In "Election Day" Phil gives Walt a ride to pick up his glasses. When Walts' tank starts to run out, Phil panics when he says that he doesn't have any more tanks at home and forgot to order them, and when he says that he needs to take his pill, which he does have, he says he needs it with food. So Phil drops him off at the polling station where they need to vote for Claire, Walt gets food to take with his pill first so that he'll be okay. Walt says that he doesn't like to vote for the government as they seem to screw him over, but since he had such a nice day with Phil, who says he thinks is a nice kid, he decides to vote for Claire, which goes against everything he believes in.

In "The Last Walt" In the opening scene, Phil and Claire have an "interview" where they give the news that Walt has died. Phil and Claire break the news to Luke, however Luke says that he is OK, and just wants to get back to his videogame. Later on Phil and Claire see Luke go int Walters' house, and think it's to say goodbye to (his house and spirit). Phil and Claire then see Luke come out and take Walts' TV with him. A while later Luke brings Claire to Walts' house and Claire begins to get worried when Luke doesn't want to say a few words about how he felt about Walt and thinks that he isn't dealing with it in a healthy way. In the same scene Claire realises that she can't tell people someone has died without smiling, which is a coping mechanism for her, and Luke opens up about how he feels about Walt dying, Claire then comforts him although Luke still doesn't cry.

Sexual Behavior

Luke was first not so much interested about having girlfriend or seen pornography. However, as the series has progressed and he has grown up, he has shown an interest about it in many times:

  • In "Not in My House", when Claire discovers a photo on her computer of a topless woman on a tractor, she assumes that Luke downloaded it since is the one who used last her computer. But Luke tells her that he did not download the photo because he thinks it's gross, as he is only a child. Claire finds out later that Phil downloaded it.
  • In "Baby on Board", when he realizes that Haley wants to live with Dylan, Luke asks her if she is 'doing sex' with him, and Claire tapes his mouth immediately.
  • In "New Year's Eve", he has a date with a girl, Becca, and he tries to make out with her in his room, although his sisters finally tell her to leave, threatening to call her parents.
  • In "Under Pressure", he and Manny go on a double date with twins, Zoe and Piper. At the end the date, the twins ask Luke and Manny if they want to back to there house and make out and they accept their offer.

Character Development

From Season 1 Luke is known to be very simple minded and quite dumb, doing things that could lead to disaster but never actually did. However this changes from Season 7:

In "The Verdict" Luke proves to his father that he is right about a person who he thinks has conned his Dad for money. While Phil tells him not to be so cynical Luke doesn't give up proving to his father that he is right and soon the audience is made to believe that it's evident that he is in fact right and the guy who Phil gave money to had conned him for $40 and a little extra. However at the end Luke is proved wrong when the guy tells the he is Dr. Monty the person who was in the hospital the day Luke was born as a midwife.
