Josh Gibson Field is a baseball venue located in the Hill District of Pittsburgh, Pennsylvania. Until 2008, the field was known as Ammon Field or sometimes Ammons Field, which had served as the home of the Pittsburgh Keystones of the Negro National League in 1922, their only season in the NNL. It is now named after Baseball Hall of Fame player Josh Gibson. The original name of the park honored Edith Darlington Ammon, a pioneer in establishing playgrounds in the city.
