Mapleton Park or Mapleton Oval was an urban athletic park in Brooklyn, New York.
It existed from at least 1916 to 1920, located at 62nd Street and 20th Avenue. The field was the home of the Mapleton Park Nine baseball team.[1]
The oval may have been named after an old neighborhood name for the area. Today, the legacy of the name Mapleton Park exists in a local synagogue, the Young Israel of Mapleton Park, near 65th Street and Bay Parkway (22nd Avenue).
