Albrecht, Duke and Crown Prince of Württemberg was the last heir presumptive to the Kingdom of Württemberg, a German military commander of World War I, and the head of the House of Württemberg from 1921 to his death.

The Kingdom of Württemberg was a German state that existed from 1805 to 1918, located within the area that is now Baden-Württemberg. The kingdom was a continuation of the Duchy of Württemberg, which existed from 1495 to 1805. Prior to 1495, Württemberg was a county in the former Duchy of Swabia, which had dissolved after the death of Duke Conradin in 1268.
