A horse show ringmaster, sometimes also called a ring steward, is an individual who works in the center of an arena at a horse show and carries out many duties to assist the judge and other officials.
In a few competitions, usually national championships or other shows of national importance, the ringmaster may be colorfully attired in a manner similar to the ringmaster of a circus or the bugler at a horse race.
More commonly, at ordinary horse shows, the ringmaster will simply wear neat clothing and comfortable shoes, similar to the attire of the judge.
The duties and responsibilities of a ringmaster of a horse show varies by discipline and geographical region.
Some notable individuals who have served long careers as ringmasters in the United States include Dutch White, Honey Craven, Vincent Wholey, and Paul Copanas.
