Chaka (Bulgarian: Чака; died 1300) briefly reigned as tsar of Bulgaria, from 1299 to 1300. He was the son of the Mongol leader Nogai Khan by a wife named Alaka. Sometime after 1285 Chaka married a daughter of George Terter I of Bulgaria, named Elena. In the late 1290s, Chaka supported his father Nogai in a war against the legitimate khan of the Golden Horde, Toqta. Toqta defeated and killed Nogai in 1299.
