The Cardinals were led by seventh-year head coach Tic Price and played their home games at the Montagne Center in Beaumont, Texas.

This season was the Cardinals' last as members of the Southland Conference; Lamar was one of four schools, all from Texas, that left the Southland in July 2021 to join the Western Athletic Conference.

They defeated McNeese State in the first round of the Southland tournament and were set to face Nicholls in the second round before the tournament was cancelled amid the COVID-19 pandemic.

Roster Last update: December 10, 2020 All Lamar games will be broadcast on KLVI, also known as News Talk 560.

Live video of all home games (except those picked up by Southland Conference TV agreements) will be streamed on ESPN3.
