Albert III of Brandenburg-Salzwedel

Albert III (c. 1250–1300) was an Ascanian margrave of Brandenburg-Salzwedel, son of Margrave Otto III and Beatrice of Bohemia. He was a co-ruler while his cousin Otto IV 'with the Arrow' held power, and administered Stargard, serving as lord of Stargard and Lychen from 1284.

After his sons died around 1299, he sold Stargard to his son-in-law Henry II of Mecklenburg, who held it as a Brandenburg fief under the 1304 Treaty of Vietmannsdorf. In 1299 he founded the Coeli Porta monastery at Lychen. After his death in 1300 he was buried at Lehnin Abbey.
