Otto III of Hachberg (6 March 1388 at Rötteln Castle – 14 November 1451 in Constance) was Bishop of Constance from 1410 to 1434. During this time he was the host of the Council of Constance (1414–1418). Although he was the second person named Otto in the Hachberg-Sausenberg line of the House of Zähringen, he is consistently called Otto III in the literature, because he was the third bishop of Constance named Otto.
Otto was the eldest son of Margrave Rudolf III of Hachberg-Sausenberg and his second wife, Anne of Freiburg-Neuchâtel.
