The principality of Galilee was one of the four major seigneuries of the crusader Kingdom of Jerusalem, according to 13th-century commentator John of Ibelin, grandson of Balian.

[1] The direct holdings of the principality centred around Tiberias, in Galilee proper, but with all its vassals, the lordship covered all Galilee (now Israel) and southern Phoenicia (today Lebanon).

The principality was established, at least in name, in 1099 when Tancred was given Tiberias, Haifa, and Bethsan by Godfrey of Bouillon.

The principality was destroyed by Saladin in 1187, although the title was used by relatives and younger sons of the kings of Cyprus (the titular kings of Jerusalem) afterwards, and some of its former holdings were briefly reclaimed by a treaty made during the Barons' Crusade.

Nazareth was the original site of the Latin patriarch, established by Tancred.
