Joachim Ernst, Duke of Anhalt (11 January 1901 – 18 February 1947) was the last ruler of the Duchy of Anhalt.
He succeeded his father as Duke of Anhalt on 13 September 1918. However, due to his age, his uncle Prince Aribert of Anhalt was appointed regent. His brief reign came to an end on 12 November 1918, with his uncle abdicating in his name following the German revolution. The duchy became the Free State of Anhalt.
He died at the Buchenwald concentration camp after World War II as a prisoner of the Soviet Union, when it was called NKVD special camp Nr. 2.
Following his death, the headship of the Ducal House of Anhalt was disputed between his elder son, Prince Friedrich, and brother Prince Eugen.
