This category is for queen consorts. A queen consort is the wife of a reigning king. A queen consort usually shares her husband's rank and holds the feminine equivalent of the king's monarchical titles. Generally, queen consorts do not share the king regent's political and military powers, as opposed to queens regnant, who rule in their own right.

It is not unheard of in history for a queen to be a consort in one kingdom, and a regnant in another kingdom. Some of the better known examples are Isabella I of Castile and Mary I of Scotland.
