The following is a list of baseball umpires who officiated in Major League Baseball (MLB). The list includes those who worked in any of four 19th century major leagues (American Association, National Association, Players' League, Union Association), one defunct 20th century major league (Federal League), the currently active Major League Baseball, or either of its leagues (American League, National League) when they maintained separate umpiring staffs. All of the above leagues, with the exception of the National Association, are recognized by MLB’s Special Baseball Records Committee.^[1] The NA’s status as a major league is disputed, with some researchers such as those involved with Retrosheet including it in their major league statistics.^[2]

In 2020, MLB recognized seven leagues within Negro league baseball as major leagues: the first and second Negro National Leagues (1920–1931 and 1933–1948), the Eastern Colored League (1923–1928), the American Negro League (1929), the East–West League (1932), the Negro Southern League (1932), and the Negro American League (1937–1948).^[3] The Society for American Baseball Research considers the NAL’s 1949 and 1950 seasons to also be major league seasons, with Retrosheet including 1949 in their statistics.^[4] Records of the Negro major leagues are not as complete compared to other major leagues, and therefore information about the umpires who worked in those leagues is often unavailable.

Umpires who worked in the National Association are considered MLB umpires for the purposes of this list. Umpires who worked in the recognized Negro major leagues may also be added.
