The 2017–18 NCAA Division III men's ice hockey season began on October 21, 2017, and concluded on March 24, 2018. This was the 45th season of Division III college ice hockey.

The two Division II schools, (Saint Anselm and Saint Michael's) that had played in the New England Hockey Conference for years, formally left the league and began playing a full Northeast-10 Conference schedule.

As had been announced in 2016, seven members of ECAC West, the last remaining ECAC conference at the Division III level, left to form the United Collegiate Hockey Conference along with two new men's programs. The remaining school, Hobart, joined the NEHC.
