List of major league baseball umpires

The following is a list of major league baseball umpires.

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.

[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.

Umpires who worked in the recognized Negro major leagues may also be added.
