Men’s ice hockey has been a tradition at Colby since 1922. The program excelled during the 1955-56 season under head coach Jack Kelley, former president of the Pittsburgh Penguins. That same season the team moved into its current home of Alfond Rink, which was made possible by a generous gift from Harold Alfond. The Mules compiled a 92-46-5 cumulative record over the next seven years, capping the era with a fourth-place finish in the ECAC Division I Tournament. Ten years later, with the creation of an ECAC Division II league, the Mules earned their first championship title by defeating Merrimack College 5-0 in the finals. That team was coached by the legendary Charlie Holt.

In the past 20 years the Mules have ushered in a new era of success. Colby has had 16 winning seasons in 20 years. The Mules have gained 10 NESCAC berths, an NCAA berth, six ECAC berths, and a 1997 ECAC Championship. Former head coach Jim Tortorella is the all-time leader in career coaching wins at Colby with 230. Blaise MacDonald, who brought both Division I and III coaching experience for the 2012-13 season, helped the Mules make the NESCAC playoffs in three of his four years.
