Tsarina or tsaritsa (also spelled csarina or csaricsa, tzarina or tzaritza, or czarina or czaricza; ) is the title of a female autocratic ruler (monarch) of Bulgaria, Serbia, and Russia, or the title of a tsar's wife. The English spelling is derived from the German czarin or zarin, in the same way as the French tsarine / czarine, and the Spanish and Italian czarina / zarina. (A tsar's daughter is a tsarevna.)
