Mid90s (stylized as mid90s) is a 2018 American coming-of-age comedy-drama film written and directed by Jonah Hill, in his feature directorial debut, inspired by Hill's own childhood in the mid-1990s. It stars Sunny Suljic, Lucas Hedges and Katherine Waterston, and follows a 13-year-old boy who begins spending time with a mostly older group of skateboarders while living in 1990s Los Angeles.

The film had its world premiere at the Toronto International Film Festival on September 9, 2018, and was theatrically released in the United States on October 19, 2018, by A24. It was well received by critics, who called it a "promising first outing for Hill", and praised the sense of nostalgia.
