This category lists queens regnant. A queen regnant (plural "queens regnant") is a female monarch who reigns in her own right, in contrast to a "queen consort", who is the wife of a reigning king. There have been instances in history of a queen regnant ruling jointly with a king regnant, as well as queens ruling in their own right in one realm, while being a consort in another, and consorts overthrowing their husbands to become self-sufficient monarchs.
