The 2003 Big 12 Conference baseball tournament was once again held at AT&T Bricktown Ballpark in Oklahoma City, OK (after a one-year hiatus) from May 21 through 25. Texas won their second consecutive tournament and earned the Big 12 Conference's automatic bid to the 2003 NCAA Division I baseball tournament. The tournament mirrored the format of the College World Series, with two 4-team double-elimination brackets and a final championship game.
