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 adulthood; two of his older brothers, Frederick Maurice and Henry Waldemar, died in infancy.
