UFC 9: Motor City Madness was a mixed martial arts event held by the Ultimate Fighting Championship on May 17, 1996, at the Cobo Arena in Detroit, Michigan. The event was seen live on pay per view in the United States, and later released on home video.

UFC 9 was the first UFC production not to feature the tournament format (which was brought back by popular demand at UFC 10). Instead, it featured an entire card of predetermined matchups. The card featured seven bouts and an alternate bout to fill time for the pay-per-view broadcast.

The main event the was the highly anticipated rematch between reigning UFC Superfight Champion Ken Shamrock and number one contender Dan Severn, who had fought one year earlier at UFC 6 for the UFC Superfight Championship, with Shamrock reigning victorious.

The UFC drew national criticism leading up to the event, due in large part to Arizona Senator John McCain's letter writing campaign against the "brutal spectacle" of no holds barred fighting. After a legal battle in the Detroit courts up until 4:30 p.m. on the day of the show, the UFC was allowed to continue, but with modified rules.
