The SIU Edwardsville Cougars baseball team represents Southern Illinois University Edwardsville in NCAA Division I college baseball. They compete as members of the Ohio Valley Conference. SIUE plays its home games at Roy E. Lee Field at Simmons Baseball Complex, located in the northwest corner of the campus.
The Cougars baseball program was started in 1967–68 by Roy Lee, who headed it for its first eleven years. In that time, his teams built a record of 237–144–3, going to 8 consecutive NCAA Division II playoffs and 3 Division II College World Series, with a runner-up finish in 1976.
After Coach Lee's retirement, the program was led for 34 years by SIUE alumnus Gary Collins. Collins' teams won 1028 games (with 766 loses & 7 ties). While still in Division II, his teams made 14 NCAA appearances and went to the Division II College World Series 5 times. He led them into Division I and the Ohio Valley Conference, where the Cougars completed their first season in the OVC in 2012 with an overall record of 27–28 and a conference record of 13–14, which tied for fifth place in the ten-team league.
In 2012, Gary Collins moved from coaching to become SIUE's first Director of Development for Intercollegiate Athletics.
With Collins' job change, after thirteen seasons as Collins' assistant, SIUE alumnus Tony Stoecklin was named acting head coach for 2013 and continued as head coach from 2014.
The 2014 squad became the first to qualify for the OVC Baseball Tournament, earning the No. 4 seed in the six team field.
Stoecklin was reassigned within the athletic department in mid-April 2016, with assistant Danny Jackson named as interim coach and a national search for a new coach to be launched after the season.
On June 24, 2016, Sean Lyons, the associate head coach at Bradley, was named the fourth head coach in Cougars' history.
