Elizabeth the Cuman (1244–1290) was the Queen consort of Stephen V of Hungary. She was regent of Hungary during the minority of her son from 1272 to 1277.

Stephen V was King of Hungary and Croatia between 1270 and 1272, and Duke of Styria from 1258 to 1260. He was the oldest son of King Béla IV and Maria Laskarina. King Béla had his son crowned king at the age of six and appointed him Duke of Slavonia. Still a child, Stephen married Elizabeth, a daughter of a chieftain of the Cumans whom his father settled in the Great Hungarian Plain.
