William Bradley Pitt was born on December 18, 1963, in Shawnee, Oklahoma, to William Alvin Pitt, the proprietor of a trucking company, and Jane Etta (née Hillhouse; 1940–2025), a school counselor. The family soon moved to Springfield, Missouri, where he lived together with his younger siblings, Doug Pitt (born 1966) and Julie Neal (née Pitt) (born 1969). Born into a conservative Christian household, he was raised as Southern Baptist and later "oscillate[d] between agnosticism and atheism". He later reconciled his belief in spirituality. Pitt has described Springfield as "Mark Twain country, Jesse James country", having grown up with "a lot of hills, a lot of lakes".

Pitt attended Kickapoo High School, where he was a member of the golf, swimming, and tennis teams. He participated in the school's Key and Forensics clubs, in school debates, and in musicals. Following his graduation from high school, Pitt enrolled in the University of Missouri in 1982, majoring in journalism with a focus on advertising. As graduation approached, Pitt did not feel ready to settle down. He loved films—"a portal into different worlds for me"—and, since films were not made in Missouri, he decided to go to where they were made. Two weeks short of completing the coursework for a degree, Pitt left the university and moved to Los Angeles, where he took acting lessons and worked odd jobs. He has named Gary Oldman, Sean Penn, and Mickey Rourke as his early acting heroes.

While struggling to establish himself in Los Angeles, Pitt took lessons from acting coach Roy London. His acting career began in 1987, with uncredited parts in the films No Way Out (1987), No Man's Land (1987) and Less than Zero (1987). In May 1987, he made his television debut in a two-episode role on the NBC soap opera Another World. In November of the same year, Pitt had a guest appearance on the CBS sitcom Trial and Error and the ABC sitcom Growing Pains. He appeared in four episodes of the CBS primetime series Dallas between December 1987 and February 1988 as Randy, the boyfriend of Jenna Wade's daughter Charlotte (played by Shalane McCall). Later in 1988, Pitt made a guest appearance on the Fox police drama 21 Jump Street. In the same year, the Yugoslavian–American co-production The Dark Side of the Sun (1988) was his first leading film role, starring as a young American taken by his family to the Adriatic to find a remedy for a skin condition. The film was shelved at the outbreak of the Croatian War of Independence, and was not released until 1997. Pitt made two motion picture appearances in 1989: the first in a supporting role in the comedy Happy Together; the second a featured role in the horror film Cutting Class, the first of Pitt's films to reach theaters. He made guest appearances on television series Head of the Class, Freddy's Nightmares, Thirtysomething, and (for a second time) Growing Pains.

Pitt was cast as Billy Canton, a drug addict who takes advantage of a young runaway (played by Juliette Lewis) in the 1990 NBC television movie Too Young to Die?, the story of an abused teenager sentenced to death for a murder. Ken Tucker of Entertainment Weekly wrote: "Pitt is a magnificent slimeball as her hoody boyfriend; looking and sounding like a malevolent John Cougar Mellencamp, he's really scary." The same year, Pitt co-starred in six episodes of the short-lived Fox drama Glory Days and took a supporting role in the HBO television film The Image. His next appearance came in the 1991 film Across the Tracks; Pitt portrayed Joe Maloney, a high school runner with a criminal brother, played by Ricky Schroder. The same year he featured in a Levi's jeans TV commercial based around the song "20th Century Boy" which played in the background.
