The 2019–20 NCAA Division III men's ice hockey season began on November 1, 2019, and concluded on March 8, 2020.

This was the 47th season of Division III college ice hockey.

Two days before the National Tournament was set to begin, the championship, along with all other NCAA events for the spring semester, was cancelled due to the Coronavirus outbreak.

The new method used was a convoluted arrangement where a team's conference record would still be recorded based upon the standard NCAA format where wins and losses accrued in the 5-minute 5-on-5 overtime were included in the win column.

Teams that recorded a tie would follow a more typical situation where they would receive one additional point for a 3-on-3 overtime win or a shootout win but would not receive any additional points for a loss in either case.
