The 2012–13 Big Ten men's basketball season began with practices in October 2012, followed by the start of the 2012–13 NCAA Division I men's basketball season in November. Conference play began in early-January 2013, and concluded in March with the 2013 Big Ten men's basketball tournament at the United Center in Chicago. All conference regular season and tournament games were broadcast nationally. For the 37th consecutive season, the conference led the nation in attendance.

The 2012–13 Michigan Wolverines men's basketball team represented the University of Michigan during the 2012–13 NCAA Division I men's basketball season. The team played its home games in Ann Arbor, Michigan, at the Crisler Center. This season marked the team's 96th consecutive year as a member of the Big Ten Conference, and it is occasionally referred to as "Team 96". The team was led by sixth-year head coach John Beilein. As the defending 2011–12 Big Ten Conference men's basketball season regular season co-champions, the Wolverines finished fourth in the conference in 2012–13 and as National Runner-up in the 2013 NCAA Division I men's basketball tournament after losing in the championship game to Louisville. Louisville's win was later vacated due to the 2015 University of Louisville basketball sex scandal. The team achieved a 31–8 record, the most wins by the program in 20 seasons.
