2017–18 Metro Atlantic Athletic Conference men's basketball season

The 2017–18 Metro Atlantic Athletic Conference (MAAC) men's basketball season began with practices in October 2017, followed by the start of the 2017–18 NCAA Division I men's basketball season on November 10. Conference play started in January and concluded on March 15, 2018. This was the 37th season of MAAC basketball.

On February 25, 2018, the last day of the MAAC regular season, both Rider and Canisius won their final game to claim a share of the MAAC Regular Season title. Rider and Canisius both split their regular season games, but Rider had a 1–0 record against third place Niagara and Canisius went 1–1, so Rider was awarded the No. 1 seed in the 2018 MAAC tournament, while Canisius secured the No. 2 seed.

The 2018 MAAC Tournament was held from March 1–5, 2018 at the Times Union Center in Albany, NY. No. 4 seed Iona defeated No. 6 seed Fairfield 83–71 to win the tournament championship, their third consecutive. They joined former member La Salle University (1988–90) and Siena College (2008–10) as the only teams to ever win three consecutive tournament championships. No team has won four consecutive as of 2018. As a result, Iona received the conference's automatic bid to the NCAA tournament. They earned a No. 15 seed and lost to No. 2 seed Duke 67–89 in the first round. Rider, a conference champion who failed to win its conference's tournament, received a bid to the National Invitation Tournament, losing 86–99 at Oregon. Canisius was invited to play in the College Basketball Invitational, and lost at home to Jacksonville State 78–80OT in the first round. Niagara was invited to the CollegeInsider.com Tournament, and lost at Eastern Michigan 65–83.
