Konostaulos or konostablos ("constable", in Greek variously κονόσταυλος, κονοσταῦλος or κονόσταβλος), later corrupted to kontostaulos/kontostablos (κοντόσταυλος), was a late Byzantine title, adopted from the Normans. The derivative dignity of megas konostaulos (μέγας κονόσταυλος, "Grand Constable") became one of the highest court posts in the Palaiologan period (1261–1453) and was awarded to high-ranking generals.
