The Norwegian Crusade, led by Norwegian King Sigurd I, was a crusade or a pilgrimage that lasted from 1107 to 1111, in the aftermath of the First Crusade. The Norwegian Crusade marks the first time a European king personally went to the Holy Land.

The Crusades were a series of religious wars initiated, supported, and sometimes directed by the Christian Latin Church in the medieval period. The best known of these military expeditions are those to the Holy Land in the period between 1095 and 1291 that had the objective of reconquering Jerusalem and its surrounding area from Muslim rule after the region had been conquered by the Rashidun Caliphate centuries earlier. Beginning with the First Crusade, which resulted in the conquest of Jerusalem in 1099, dozens of military campaigns were organised, providing a focal point of European history for centuries. Crusading declined rapidly after the 15th century.
