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.
This list includes all ballparks that served as regular home fields for teams throughout all six circuits' histories as major leagues.
All playing fields are natural grass unless otherwise noted.
