The mitre (Commonwealth English) (/ˈmaɪtər/; Greek: μίτρα, 'headband' or 'turban') or miter (American English; see spelling differences) is a type of headgear now known as the traditional, ceremonial headdress of bishops and certain abbots in traditional Christianity. Mitres are worn in the Catholic Church, Eastern Orthodox Church, Oriental Orthodox Churches, the Anglican Communion, some Lutheran churches, for important ceremonies, by the Metropolitan of the Malankara Mar Thoma Syrian Church, and also, in the Catholic Church, all cardinals, whether or not bishops, and some Eastern Orthodox archpriests.
