Frederick III of Baden

Frederick III, called the Peaceful (1327 – 2 September 1353), was Margrave of Baden from 1348 until his death. The elder son of Margrave Rudolf IV and Marie, he and his brother Rudolf V took power together after their father's death and divided the inheritance: Frederick made Baden-Baden his residence while Rudolf ruled Baden-Pforzheim.

Around 1345 he married Margareta, daughter of Margrave Rudolf Hesso of Baden-Baden; their son Rudolf VI later reunited the margraviate. Frederick died on 2 September 1353.
