The Illinois Fighting Illini men's ice hockey team is a college ice hockey program that represents the University of Illinois at Urbana–Champaign. The Illini play on campus at historic 1,500-seat University of Illinois Ice Arena. They are a member of the American Collegiate Hockey Association (ACHA) at the ACHA Division I level. The team is a former member of the Central States Collegiate Hockey League (CSCHL) within the ACHA. The team operates as a registered student organization (RSO) at the University of Illinois. The university does not currently have an NCAA varsity team, and thus the club team is the highest level of hockey offered by the university. A feasibility study published in March 2018, and commissioned by the NHL, NHLPA, and College Hockey, Inc., found a high probability of success for the hockey program to transition to NCAA Division I. Illinois however reversed course in May 2022, announcing that they were no longer exploring adding a varsity hockey program.

The Illinois Fighting Illini are the intercollegiate athletic teams that represent the University of Illinois Urbana-Champaign. The university offers 10 men's and 11 women's varsity sports.
