2017–18 Ivy League men's basketball season

The 2017–18 Ivy League men's basketball season marked the continuation of the annual tradition of competitive basketball among Ivy League members. The tradition began when the league was formed during the 1956–57 season and its history extends to the predecessor Eastern Intercollegiate Basketball League, which was formed in 1902.

Harvard and Pennsylvania co-shared the league title after finishing the regular season 12–2 within the Ivy League. Pennsylvania earned the league's bid to the 2018 NCAA Men's Division I Basketball Tournament after defeating Yale in the semifinals and Harvard in the finals of the inaugural conference tournament.

Seth Towns of Harvard was named Ivy League Men's Basketball Player of the Year.
