The following is a list of ballparks previously used by professional baseball teams. In addition to the current National (NL) and American (AL) leagues, Major League Baseball recognizes four short-lived other leagues as "major" for at least some portion of their histories; three of them played only in the 19th century, while a fourth played two years in the 1910s. These leagues are the American Association (AA), 1882–1891; the Union Association (UA), 1884; the Players' League (PL), 1890; and the Federal League (FL), 1914–1915. This list includes all ballparks that served as regular home fields for teams throughout all six circuits' histories as major leagues.
