Herman(n) of Salm (ca. 1035 – 28 September 1088), also known as Herman(n) of Luxembourg, was a count of Salm and German anti-king of the Holy Roman Empire who ruled from 1081 until his death. From the 10th century, the rulers of the Holy Roman Empire were elected German kings, who expected to be crowned by the Pope as Holy Roman Emperor.

Hermann was a son of Count Giselbert of Luxembourg. While Henry IV, Holy Roman Emperor, King of the Romans, was campaigning in Northern Italy during the Great Saxon Revolt civil war, Hermann was elected as the second anti-King of Germany opposed to the emperor-elect in Ochsenfurt on 6 August 1081, by the nobility of Saxony and Swabia. Siegfried I, Archbishop of Mainz, crowned Hermann in Goslar on 26 December. Hermann's predecessor, Rudolph of Swabia, had died from wounds received in the battle of in October of 1080. Because Henry believed the papacy should submit to the crown, Pope Gregory VII had excommunicated him and declared that he was unworthy of being the Holy Roman Emperor. The civil war eventually ended and Henry was crowned Emperor by Pope Gregory VII in 1084, leaving Hermann in a very awkward position. -------------------- Herman(n) of Salm (ca. 1035 – 28 September 1088), also known as Herman(n) of Luxembourg, was a a count of Salm and German anti-king of the Holy Roman Empire who ruled from 1081 until his death.
