The ECAC Men's Basketball Tournaments are postseason college basketball tournaments organized by the Eastern College Athletic Conference (ECAC). Despite its name, the ECAC is not a traditional athletic conference, but rather a loosely organized sports federation for colleges and universities in the eastern United States. Among other things, it organizes end-of-season college basketball tournaments for member schools which are not members of a traditional conference, or which do not otherwise have access to such a tournament. At various times, it has organized end-of-season basketball tournaments at the National Collegiate Athletic Association (NCAA) Division I, Division II, and Division III levels.
