The Virginia Cavaliers are the athletics teams officially representing the University of Virginia in college sports. The Cavaliers participate in the NCAA's Division I Atlantic Coast Conference in 25 varsity sports. The athletics program has won 15 recognized team national championships , third-highest total of national titles in the conference after UNC with 32 and Maryland with 20.

The media generally refers to the University's athletic teams as simply Virginia for short, and the mascot is a mounted swordsman, or "Cavalier". (This mascot is a historical reference to the time when Virginia earned its nickname, the "Old Dominion". The Commonwealth was a hotbed of persons loyal to the English crown, called cavaliers in the days of the English Civil War and Interregnum.) An unofficial moniker, the Wahoos, or 'Hoos for short, based on the University's rallying cry "Wah-hoo-wah!" is also commonly used. Though originally only used by the student body, both terms — Wahoos and Hoos — have come into wide use by the media as well.
