This is a list of Big East Conference men's basketball regular season champions.
There are no tie-breakers for the Regular Season Championship, so any teams tied for first at the end of the season share the Championship.
The original Big East Conference began play in the 1979–80 season.
After the end of the 2012–13 season, seven schools left that conference to join three other schools in forming a new Big East Conference which began play in the 2013–14 season, while the old conference renamed itself the American Athletic Conference, marketed as "The American."
