The 2020 Oklahoma State Cowboys baseball team represented Oklahoma State University during the 2020 NCAA Division I baseball season. The Cowboys played their home games at Allie P. Reynolds Stadium through March 15 and at O'Brate Stadium beginning March 20 as a member of the Big 12 Conference. They were led by head coach Josh Holliday, in his 8th season at Oklahoma State.
On March 13, the Big 12 Conference canceled the remainder of the season due to the Coronavirus pandemic.
The 2019 Oklahoma State Cowboys baseball team notched a 32âÂÂ17 (14âÂÂ9) regular season record and finished third in the Big 12 Conference standings. The Cowboys reached the 2019 Big 12 Conference baseball tournament championship game, where they defeated West Virginia to claim the program's third Big 12 title. Oklahoma State received the Big 12 Conference's automatic bid to the 2019 NCAA Division I baseball tournament and was selected as one of the sixteen Regional hosts (played in Oklahoma City). The Cowboys defeated Harvard, Nebraska, and Connecticut to win the Oklahoma City Regional but were eliminated from the NCAA tournament by Texas Tech in the Lubbock Super Regional.
