Iona University has been competing in Division I basketball since the school's inception in 1940. Their first taste of success came with the
ECAC men's basketball tournaments (essentially regional tournaments played by Division I schools that were essentially independent, with Iona being in the Metro) in 1979 and 1980, winning the two years for an autobid to the NCAA Tournament. Iona is also one of the founding members of the
Metro Atlantic Athletic Conference, which began play in men's basketball with the 1981–82 season, having been passed over by the
Big East Conference for Seton Hall in 1980. The Gaels have compiled the most victories of any MAAC team since the founding of the conference and have won a league record fourteen MAAC tourney titles (1982, 1984, 1985, 1998, 2000, 2001, 2006, 2013, 2016, 2017, 2018, 2019, 2021, and 2023). They have appeared in the NCAA tournament in 1979, 1980, 1984, 1985, 1998, 2000, 2001, 2006, 2012, 2013, 2016, 2017, 2018, 2019, 2021 and 2023, with the first two of those appearances coming as a member of the Metropolitan Conference and in 2012 as an at-large selection out of the MAAC. The Gaels have also been to 7 NITs, in 1982, 1983, 1996, 1997, 2014, 2015 and 2022. In 2011, the Gaels made it to the final game of the CIT post-season tournament, losing at home to Santa Clara. Since the 1978–79 season, the Gaels have won 20 games or more in 23 seasons.
