Clemens Field is a baseball stadium located at 403 Warren Barrett Drive, at the south end of downtown Hannibal, Missouri, United States. The stadium was named for author Samuel Clemens (who wrote under the name Mark Twain), a Hannibal resident. Built in 1938 (to replace the first field that was destroyed by fire), Clemens Field has served as a home for numerous minor league baseball teams. The ballpark underwent extensive renovations in 2008, and was most recently the home of the Hannibal Hoots of the collegiate summer Prospect League.
