Mid90s (stylized in all lowercase) is a 2018 American coming-of-age comedy-drama skate film written and directed by Jonah Hill, in his feature directorial debut. The plot follows Stevie, a 13-year-old boy in 1990s Los Angeles. To escape a troubled home life, he begins spending time with an older group of skateboarders. The cast includes Sunny Suljic, Lucas Hedges, Na-Kel Smith, Alexa Demie, and Katherine Waterston.

Mid90s served as a passion project for Jonah Hill, who was inspired by his experiences growing up in Los Angeles in the 1990s. Influenced by filmmakers like Martin Scorsese and Spike Jonze, Hill aimed to authentically portray 1990s skate culture. Filming took place in various Los Angeles neighborhoods. Mid90s was filmed with a 4:3 aspect ratio reminiscent of VHS skate tapes, using Super 16mm film stock on skate videos. The soundtrack featured 1990s hip hop music.

The film had its world premiere at the Toronto International Film Festival on September 9, 2018, and was released theatrically 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. It grossed $9.3 million at the box office on a budget of $1.7 million.
