The Middle Atlantic Conferences men's basketball tournaments are the annual conference basketball championship tournaments for the NCAA Division III Middle Atlantic Conferences: the MAC Commonwealth and MAC Freedom.
The MAC has held a tournament more or less every year since 1947, although the current two-conference format has only been played since 2001.
They are each a single-elimination tournament and seeding is based on regular season records.
[1] The winners, each declared champion of their respective conference, receives one of the MAC's two automatic bids to the NCAA men's Division III basketball championship.
