Siege of Jerusalem is the title commonly given to an anonymous Middle English epic poem created in the second half of the 14th century (possibly ca. 1370-1380). The poem is composed in the alliterative manner popular in medieval English poetry, epecially during the period known as the "alliterative revival", and is known from nine surviving manuscripts, an uncommonly high number for works of this time.

The siege of Jerusalem was a complex series of military and terrorist events beginning on December 1, 1947 and lasting through January, 1949. The siege was initiated by local Palestinian Arab militias immediately after the United Nations adopted a resolution ordering partition of Palestine into Jewish and Arab states. The siege was continued by the Transjordan Arab Legion, assisted by British officers and by the Egyptian Army until the signing of the 1949 Armistice Agreements.
