Herman(n) of Salm (c. 1035 – 28 September 1088), also known as Herman(n) of Luxembourg, the progenitor of the House of Salm, was Count of Salm and elected German anti-king from 1081 until his death.

Hermann was a son of Count Giselbert of Luxembourg (1007–1059). His elder brother Conrad inherited the County of Luxemburg and became a faithful supporter of the Salian king Henry IV of Germany in the Investiture Controversy and the civil war of the Great Saxon Revolt.

The major issue between Pope Gregory VII and Henry IV was the appointment of bishops. It was a custom that if a bishop was to die, the emperor would appoint a new bishop based on his ecclesiastical qualifications. Henry, on the other hand, was appointing bishops for political reasons which made Gregory furious and thus prohibited the appointments of investiture by any lay person, including the emperor.

From the 10th century, the rulers of the Holy Roman Empire were elected Kings of the Romans, who expected to be crowned by the Pope as Holy Roman Emperor. However, because Henry believed the papacy should submit to the crown, Pope Gregory had him excommunicated and declared that he was unworthy of being Emperor. Because of this, the church broke off from Henry and supported the election of German anti-kings.

Upon Henry's humiliating Walk to Canossa, several princes met at Forchheim and had the Swabian duke Rudolf of Rheinfelden elected anti-king in 1077. Henry's and Rudolf's forces met in the 1080 Battle on the Elster, whereby Rudolf died from the wounds he received.
