The 2020 BYU Cougars baseball team represented Brigham Young University during the 2020 NCAA Division I baseball season. Mike Littlewood acted as head coach of the Cougars for an eighth consecutive season. The Cougars were picked to finish second in the WCC Pre-season poll. However they secured more first place votes from the WCC Media than any team with 5 and were named the team to beat by Baseball America. The Cougars never got to play in conference though as all athletic events were shut down by the school March 12 due to COVID-19.
