2023 MLB World Series Umpire Roster

Major League Baseball assigned seven umpires to the 2023 MLB World Series featuring the Texas Rangers and Arizona Diamondbacks. Bill Miller will serve as crew chief while Alfonso Marquez will be backup chief. Five of the seven-person crew are officiating their first career World Series.

Crew Chiefs are indicated in bold text and by the -cc suffix with regular season crew chiefs denoted by an asterisk (*). Those working their first World Series are marked with ^1st WS^. The following listings feature Game 1 configurations such that the plate umpire from Game 1 will work right field in Game 2, and all other umpires will move clockwise (e.g., 3B becomes 2B). Games 4 and 5 plates are if necessary. All World Series umpires are taken from a pool of umps who officiated the 2023 AL and NL Division Series.
