Dow Diamond is a Minor League baseball stadium located in Midland, Michigan. It is the home of the Great Lakes Loons of the Midwest League. The Loons are affiliated with the Los Angeles Dodgers.

The stadium is located near Buttles, Ellsworth and State streets in Midland. The Dow Chemical Company, whose world headquarters are in Midland, donated the land for the stadium and also purchased the naming rights to the facility in 2006. The stadium name is a reference to both Dow's logo (a red diamond) and that "diamond" is a slang term for a baseball field.
