2020–21 Arizona State Sun Devils men's ice hockey season

The Sun Devils represented Arizona State University and were coached by Greg Powers, in his 11th season.

That, and playing against stronger competition that previous years, led to the Sun Devils' facing an uphill battle in their pursuit of a second NCAA berth.

When the dust settled, ASU's record had plummeted and the team had virtually no chance of making the national tournament.
