Benoît Magimel was born in Paris on 11 May 1974. His mother was a nurse and his father worked in a bank. Through his maternal grandfather he is of Hungarian Jewish descent. He has a brother, Arnaud, and a sister, Bénédicte.

In 1988, he landed his first film role in Étienne Chatiliez's comedy Life Is a Long Quiet River, in which he played Maurice "Momo" Groseille. At sixteen, while in première (the second year of lycée), Magimel left school without a diploma to pursue acting as a career.

For his second film, the Christine Lipinska-directed comedy Papa est parti, maman aussi (1989), his name appeared at the top of the bill alongside Sophie Aubry and Jérôme Kircher.

He spent the decade accumulating roles, on television and in cinema, growing up in front of the camera, often under the direction of respected filmmakers.

In 1995, Magimel appeared as boyfriend Rémi in Benoît Jacquot's New Wave-style drama A Single Girl, which stars Virginie Ledoyen as a hotel waitress who discovers she is pregnant. That same year, Magimel made a brief appearance in Mathieu Kassovitz's black-and-white banlieue drama La Haine, which went on to become a cult film.
