Jacob David "Jake" Harper is a fictional character portrayed by Angus T. Jones in the American sitcom Two and a Half Men.

Jake is ten years old at the start of the series.Jake is the son of Alan Harper and Judith Harper and the nephew of Charlie Harper. A recurring theme with his character is having really low grades and eating a lot.He is the butt of many jokes in the show due to his general lack of smarts and self confidence. He is a reasonably nice kid but he's also lazy and unmotivated, particularly when it comes to his schoolwork (he barely passed into high school). Alan once hoarded money from his chiropractic clinic by saying he couldn't count on Jake to support him when he grew old, saying, "The only hope for him is if missing the toilet becomes a professional sport." His grandmother Evelyn has said she will pay for Jake's college education and buy him a car when/if he gets into a university, but she also discovered that, somewhat surprisingly, Jake is an excellent cook, which might be a viable career path for the food-loving lad. Jake also likes to undertake expensive hobbies and then give up on them, which annoys Alan because he has to pay for them under his child support agreement. When Alan fell into a depression after his second divorce, Jake told his father that he loved him but added, "You're my dad...I pretty much HAVE to love you."

Contrary to popular belief, Jake does not sing the intro song and the "half men" refers to the fact that Jake is "half an adult". While Jake is one of the three central characters, he is featured less than Charlie Harper and Alan Harper and there have been some episodes where he is not in any central story lines and is only heard from briefly. Alan once told a date that his ex-wife Judith has primary custody of Jake, which explains where Jake is when he's not around his father and uncle.

Throughout the sixth season no one knows that Jake found out what happened between Alan and Judith---except Charlie---because Jake wanted to make sure it wasn't the truth but Charlie told him it was. Jake thinks its cool because he wants to see Judith's reaction if his half sister is his full sister.

Jake can also play the guitar. Originally it was a form of rebellion, but it eventually became a hobby. When he first introduced his guitar skills into the show he wasn't very good, but he has drastically improved as he helped Charlie Harper to write a song for a Japanese kids' T.V. show in exchange for Cliff Notes for Lord of the Flies.
