FNB Field is a baseball park in Harrisburg, Pennsylvania, on City Island in the Susquehanna River.

The facilities include volleyball courts, softball fields, a football/soccer field, water golf, nature tails, jogging paths, cycling paths, two marinas, the Pride of the Susquehanna paddlewheel riverboat, a food court called RiverSide Village, and a miniature train that runs around the island for tours.

The stadium was used as the spring training facility in the movie Major League II, starring Charlie Sheen, Tom Berenger and Corbin Bernsen.

The changes and additions to FNB Field for the 2009 season were: A public plaza and entrance was constructed in the left field corner; a boardwalk surrounding the outfield was constructed between the foul poles; a complete upgrade to the scoreboard; a new left field seating area; an outfield bar complete with drink rails; and new seating underneath the scoreboard; a new outfield wall constructed with static advertisement panels; and a new 8,600-square-foot (800 m2) Operations Building which houses the Senators front offices, ranger, security, first aid and the new box office along with the new Senators souvenir store, concession stand, and public rest rooms.

[11] This project included the comprehensive changes to FNB Field that turned the stadium on City Island into one of the best and most unusual ballparks in minor league baseball.

With the renovation of the park, and the addition of the boardwalk, some of the distances have changed, with left and right field now 325 feet from home plate.
