1985 NCAA Division I men's basketball tournament

The 1985 NCAA Division I men's basketball tournament involved 64 schools playing in single-elimination play to determine the national champion of men's NCAA Division I college basketball. This was the first year the field was expanded to 64 teams, from 53 in the previous year's tournament. It began on March 14, 1985, and ended with the championship game on April 1 in Lexington, Kentucky. A total of 63 games were played.

Eighth-seed Villanova, coached by Rollie Massimino, won their first national title with a 66–64 victory in the final game over Georgetown, coached by John Thompson. Ed Pinckney of Villanova was named the tournament's Most Outstanding Player. The game, often cited as "The Perfect Game", is widely considered among the greatest upsets in college basketball history, and is the second biggest point-spread upset in Championship Game history. This Villanova team remains the lowest-seeded team to win the tournament. The Wildcats are also notable as the last Division I men's national champion to date to represent a school that did not sponsor varsity football at the time of its title (Villanova had dropped football after the 1980 season and did not reinstate the sport until the 1985 season, the first after the championship game). The game is also notable as the last played without a shot clock.

This year's Final Four saw an unprecedented and unmatched three teams from the same conference, with Big East members Villanova and Georgetown joined by St. John's. The only "interloper" in the Big East party was Memphis State, then of the Metro Conference (Memphis State's 1985 Final Four appearance was vacated due to using ineligible players, as were all of its tournament appearances from 1982 to 1986). Lehigh, champion of the East Coast Conference Tournament, became the first team in NCAA Tournament history to compete with a record below .500, as they were 12–18 at the time they played in the First Round.

This was also the first year that one of the regionals was named "Southeast", replacing "Mideast". This name was used until 1998, when the regional was renamed "South". This was also the last tournament until 2010 to feature two private schools in the title game. This tournament was also the last until 2012 to feature no teams in the Sweet 16 from the Mountain or Pacific Time Zones.

This tournament's East Region is the only one in NCAA Tournament history in which the higher-seeded team won every game.
