The 1983–84 NCAA Division III men's ice hockey season began in November 1983 and concluded on March 23 of the following year.
This was the 11th season of Division III college ice hockey.
This was the first season in which the NCAA held a national tournament for the Division III level.
Additionally, with an NCAA-sponsored tournament for Division III schools, most NAIA teams switched to NCAA classification and, with the NAIA Ice Hockey Championship becoming a superfluous tournament, the NAIA ended its sponsorship of ice hockey in 1984.
The NCAA continued to refrain from offering automatic bids until 2000.
