What is the difference between a referee, an umpire and a judge?
All three are match officials, and the terms are not interchangeable — they reflect different positions relative to play and different kinds of decision.
A referee typically operates within the field of play, moving with the action, and has broad discretionary authority over the whole contest.
Used in football, rugby, basketball and boxing. The referee applies judgement continuously: whether contact was a foul, whether to play advantage, whether to caution or dismiss. In football the referee is explicitly the sole arbiter of fact, and the role carries substantial interpretive latitude.
The word's origin reflects this — matters were referred to them for a ruling.
An umpire typically operates from a fixed position outside or at the edge of play, and makes more discrete, factual determinations.
Used in cricket, tennis, baseball and hockey. The decisions are frequently binary: in or out, ball or strike, out or not out. There is less continuous interpretation and more adjudication of specific events.
The distinction is not absolute — cricket umpires make judgement calls constantly under LBW, and American football uses both terms for different officials on the same crew.
A judge scores rather than adjudicates. Judges do not rule on whether something was legal; they evaluate quality and award marks.
Used in gymnastics, diving, figure skating, boxing and dressage. Multiple judges score independently, and systems typically discard the highest and lowest to limit the effect of an outlier or a biased official — an explicit acknowledgement that scoring is subjective.
Other official titles:
Assistant referee — the modern term for a linesman in football.
Fourth official, managing the technical area.
Video officials — VAR in football, the TMO in rugby, DRS in cricket.
Marshals and stewards in motorsport and racing, managing safety rather than rules.
Starters in athletics and swimming.
Timekeepers, and in boxing the separate roles of referee and judges, where the referee controls safety and the judges score.
