Pat Casey (born 1959) is the head coach for the Oregon State Beavers baseball team. He is best known for winning the 2006 College World Series for the Beavers' first-ever baseball National Championship. Despite losing all but two starters on the team and being selected last in the NCAA College World Series bracket, he led the Beavers to a repeat championship in the 2007 College World Series, the first unranked team in history to accomplish this feat.
