The 2022 Lamar Cardinals football team represented Lamar University in the 2022 NCAA Division I FCS football season. The Cardinals played their home games at Provost Umphrey Stadium in Beaumont, Texas, and competed in the Southland Conference following an early return from the Western Athletic Conference. On July 11, 2022, Lamar announced that they would take an early transition back to the Southland Conference after the athletic department announced back in April 2022 a transition back to the conference for the 2023 season.
