Taxiarch, the anglicized form of taxiarchos or taxiarchēs () is used in the Greek language to mean "brigadier". The term derives from táxis, "order", in military context "an ordered formation". In turn, the rank has given rise to the Greek term for brigade, taxiarchia. In Greek Orthodox Church usage, the term is also applied to the Archangels Michael and Gabriel, as leaders of the heavenly host, and several locations in Greece are named after them.
