The 1982–83 William & Mary Tribe men's basketball team represented the College of William & Mary during the 1982–83 college basketball season. It was head coach Bruce Parkhill's sixth and final season at William & Mary before leaving for Penn State. The Tribe competed in the ECAC South and played their home games at Kaplan Arena. They finished the season 20–9 (9–0 in ECAC South competition) but lost in the championship game of the 1983 ECAC South men's basketball tournament to James Madison. They were invited to play in the 1983 National Invitation Tournament (the Tribe's first-ever postseason tournament bid and only one until 2010) where they lost in the first round to Virginia Tech. This season also marked the first-ever conference title for William & Mary's men's basketball program.
