Koch Diamond is a baseball venue in St. Paul, Minnesota, United States. It is home to the St. Thomas Tommies baseball team of the NCAA Division I Summit League. The field opened in 2006 and is named for the former St. Thomas pitcher David Koch.
The park is located along Cretin Avenue in the Union Park neighborhood of St. Paul. The outfield is also used as both a football and soccer practice facility, which results in the centerfield fence being the deepest in all of college baseball, at 465 feet.
David Koch, for whom the venue is named, pitched for the St. Thomas baseball program in 1952.
