Kutcher was born in Cedar Rapids, Iowa, to Diane (nee Finnegan), a Procter & Gamble employee, and Larry M. Kutcher, a factory worker. His father is of Czech descent, while his mother is of Czech, German, and Irish ancestry. Kutcher was raised in a "relatively conservative" Catholic family. He has an older sister named Tausha and a fraternal twin brother named Michael, who had a heart transplant when the brothers were young children.

Following his success in modeling, Kutcher moved to Los Angeles after his first audition. He was cast as Michael Kelso in the television series That '70s Show, from 1998 to 2006. Kutcher was cast in a series of film roles; although he auditioned but was not cast for the role of Danny Walker in Pearl Harbor (2001) (replaced by Josh Hartnett), he starred in several comedy films, including Dude, Where's My Car? (2000), Just Married (2003), and Guess Who (2005). He appeared in the 2003 family film Cheaper By The Dozen as a self-obsessed actor. In the 2004 drama film The Butterfly Effect, Kutcher played a conflicted young man who time travels. The film received mixed to negative reviews, but was a box office success. In 2003, Kutcher produced and starred as the host in his own series, MTV's Punk'd, that involved hidden camera tricks performed on celebrities. He is also an executive producer of the reality television shows Beauty and the Geek, Adventures in Hollyhood (based around the rap group Three 6 Mafia), The Real Wedding Crashers, and the game show Opportunity Knocks. Many of his production credits, including Punk'd, come through Katalyst Films, a production company he runs with partner Jason Goldberg. A 2004 interviewer described Kutcher as a "hunky young actor [who] is heading in all different directions at once", including "the hot L.A. restaurant Dolce": "If anything, I'm a trier," says Kutcher between puffs of filtered Lucky Strikes. "I think, more than anything, it comes from the fact that my father always had several irons in the fire. Also, I don't want to fail. If something doesn't work out--if That '70s Show got canceled or if I wasn't going to have a film career--I always wanted to have backup contingency plans. So I just started doing other things; and on a half-hour sitcom, you're really only working for 30 hours a week. It allows a lot of time for sitting around, which I always kind of filled with work." Because of scheduling conflicts with the filming of The Guardian, Kutcher was unable to renew his contract for the eighth and final season of That '70s Show, although he appeared in its first four episodes (credited as a special guest star) and returned for the series finale. Kutcher produced and starred in the 2010 action comedy, Killers, in which he played a hitman. In May 2011, Kutcher was announced as Charlie Sheen's replacement on the series Two and a Half Men. Kutcher's contract was for one year and was believed to be worth nearly $20 million. His debut as the character Walden Schmidt, entitled "Nice to Meet You, Walden Schmidt", was seen by 28.7 million people on September 19, 2011. The Nielsen ratings company reported that figure was more than any episode in the show's first eight seasons, when Sheen starred in it. Kutcher earned $750,000 an episode on the show. The show ended with a forty-minute series finale "Of Course He's Dead" on February 19, 2015.
