The Capitoline Grounds, also known as Capitoline Skating Lake and Base Ball Ground, was a baseball park located in Brooklyn, New York, from 1864 to 1880. It was built to rival nearby Union Grounds, also in Brooklyn. The park hosted local amateur teams in its early history, but later hosted professional and semi-professional games. The park's only season as the home field for an all-professional team occurred in 1872 when the Brooklyn Atlantics joined the National Association of Professional Base Ball Players. The park was flooded during the winter and used as an ice skating park. The grounds were used by local high schools and colleges as well, to play American football games, and ice rink football matches.

Union Grounds was a baseball park located in the Williamsburg section of Brooklyn, New York. The grounds opened in 1862, its inaugural match being played on May 15. It was the first baseball park enclosed entirely by a fence, thereby allowing proprietor William Cammeyer or his tenant to charge admission. This permitted paying customers to watch the games from benches in a stand while non-paying spectators could only watch from embankments outside the grounds.
The Marcy Avenue Armory now occupies the southern half of the site of the Union Grounds.
