Fieldin Henry Culbreth III (born March 16, 1963) is an American former umpire in Major League Baseball (MLB).

He has been part of the umpiring crew for two no-hitters, the first in 2010 by Matt Garza of the Tampa Bay Rays and the second by Johan Santana of the New York Mets.

[1] During the 2001 season, Culbreth received an email from then-MLB official Sandy Alderson advising him that he was not calling enough strikes and that if he did not make adjustments, he would face criticism from ESPN analysts when he umpired a game that was broadcast by the network.

Culbreth was the home plate umpire when Baltimore's Rafael Palmeiro reached the 3,000-hit milestone on July 15, 2005[1] with a double against Joel Piñeiro of the Seattle Mariners.

"[15] Prior to Johnson's apology, Culbreth was criticized by Yankees announcers John Sterling and Suzyn Waldman, neither of whom was aware of what had been said on the field.

[16] Earlier in the 2005 season, Culbreth had twice ejected Philadelphia Phillies manager Charlie Manuel from games, once in April and again in August.

[5] Culbreth was the left field umpire for the single-game playoff between the Colorado Rockies and the San Diego Padres that decided the NL's 2007 wild card team.

[18] In the 2008 World Series, which featured the Philadelphia Phillies and Tampa Bay Rays, Culbreth worked behind home plate for Game 3.

[20] In Game 3 of the 2012 World Series, Culbreth umpired behind the plate for the matchup between the Detroit Tigers and the San Francisco Giants.

[22] Culbreth was the first-base umpire for Tampa Bay Rays pitcher Matt Garza's no-hitter against the Detroit Tigers on July 26, 2010.

[24] Culbreth was at second base on June 1, 2012, when New York Mets pitcher Johan Santana threw a no-hitter against the St. Louis Cardinals.

[28][29] On September 30, 2021, during a game between the Atlanta Braves and Philadelphia Phillies, a third-party umpiring analysis Twitter bot found that Culbreth correctly called 121 of 122 taken pitches, a near-perfect performance behind the plate.

[1] As a member of an organization called BLUE for Kids, Culbreth has visited and brought presents to hospitalized children on multiple occasions.
