Margaret of Baden (1431 – 24 October 1457) was a Margravine of Baden by birth and by marriage Margravine of Brandenburg-Ansbach and Brandenburg-Kulmbach. She was the daughter of Jacob, Margrave of Baden-Baden, and his wife Catherine of Lorraine.

In 1446, Margaret married Albert of Brandenburg, the future Albert III Achilles, Elector of Brandenburg, in Heilsbronn.^[1] Margaret died before he succeeded to the Electorate of Brandenburg, thus never served as Electress. Their marriage produced three sons and three daughters:

• Ursula (1450–1508)

married in 1467 Duke Henry I of Münsterberg-Oels (1448-1498)

• Elisabeth (1451–1524)

married in 1467 Duke Eberhard II of Württemberg (1447-1504)

• Margaret (1453–1509), abbess of the Poor Clares convent at Hof from 1476
• John Cicero (1455–1499), Elector of Brandenburg

Margaret died in Ansbach in 1457 shortly after her husband acquired the Margraviate of Brandenburg-Kulmbach.
