John II of Saarbrücken
John II of Saarbrücken (1310/1313–1381) was count of Saarbrücken from 1342. The son of Simon of Saarbrücken-Commercy and Margaret of Savoy, he received the county on his grandfather John I's death in 1342, while most of Commercy went to his cousin.
He fought for France and was captured with King John II at Poitiers in 1356, imprisoned in England until 1360. He later served France on embassies to the emperor and England and was made Grand Bouteiller in 1364. He died on 11 March 1381, leaving Saarbrücken to his daughter Johanna.
