Upper Galilee

The Upper Galilee (Hebrew: הגליל העליון‎‎, HaGalil Ha'Elyon; Arabic: الجليل الأعلى‎‎, Al Jaleel Al A'alaa) is a geographical-political term in use since the end of the Second Temple period, originally referring to a mountainous area straddling present-day northern Israel and southern Lebanon, its boundaries being the Litani River in the north, the Mediterranean Sea in the west, the Lower Galilee in the south, from which it is separated by the Beit HaKerem Valley), and the upper Jordan River and the Hula Valley in the east.

In present-day Israeli terminology, the toponym is mainly used in reference to the northern part of the Galilee situated under Israeli sovereignty, i.e. without the part of Southern Lebanon up to the Litani River, while also excluding the corresponding stretches of the Coastal Plain to the west and Jordan Rift Valley to the east, which are considered separate geographical entities.

Following the dissolution of the Ottoman Empire and the Balfour Declaration in which the British Empire promised to create "A Jewish National Home" in Palestine, the Zionist Movement presented to the Versailles Peace Conference a document calling for including in the British Mandate of Palestine the entire territory up to the Litani river — with a view to this becoming eventually part of a future Jewish state.
