The UFC’s 2023 schedule is in the bag.

This past year was busy and booming not only for fighters, promoters, and coaches, but referees, as well. The UFC held events in 10 U.S. jurisdictions (Florida, Massachusetts, Missouri, New Jersey, New York, Nevada, North Carolina, Tennessee, Texas and Utah) and seven international countries ( Australia, Brazil, Canada, France, Singapore, United Arab Emirates, and the United Kingdom.

Over the span of 12 months, the UFC promoted 43 events. During those shows, 46 referees were used – a 70 percent increase in the number of referees (27) used across 43 events in 2022.

With the increased diversification of officials and locations, the number of fights refereed by last year’s leaders largely bumped down on an individual basis – and a new leader was crowned.

Below is a full list of every referee that officiated at least one UFC fight in 2023 (in alphabetical order by last name). The list does not include Dana White’s Contender Series or “The Ultimate Fighter” fights. The data was calculated using comprehensive MMA database Tapology:
