George Aribert of Anhalt-Dessau (Dessau, 3 June 1606 – Wörlitz, 14 November 1643), was a German prince of the House of Ascania and (titular) ruler of the principality of Anhalt-Dessau.
He was the sixth son of John George I, Prince of Anhalt-Dessau, but the fourth-born son of his second wife Dorothea, daughter of John Casimir of Simmern. In fact, he was the second and youngest son of John George and Dorothea who survived to adulthood; two of his older brothers, Frederick Maurice and Henry Waldemar, died in infancy.
