Galilee (Hebrew: הַגָּלִיל, HaGalil; Arabic: الجليل‎, romanized: al-Jalīl) is a region mainly located in northern Israel. The term Galilee traditionally refers to the mountainous part, divided into Upper Galilee (Hebrew: גליל עליון‎, romanized: Galil Elyon) and Lower Galilee (Hebrew: גליל תחתון‎, romanized: Galil Tahton).

In modern, common usage, as well at different times in history, Galilee referred and refers to all of the area that is north of the Mount Carmel-Mount Gilboa ridge. In this sense, it extends from the Israeli coastal plain and the shores of the Mediterranean Sea with Acre in the west, to the Jordan Rift Valley to the east; and from the Lebanese border in the north plus a piece bordering on the Golan Heights all the way to Dan at the base of Mount Hermon in the northeast, to Mount Carmel and Mount Gilboa in the south. This definition includes the plains of the Jezreel Valley north of Jenin and the Beth Shean Valley, the valley containing the Sea of Galilee, and the Hula Valley, although it usually does not include Haifa’s immediate northern suburbs. By this definition it overlaps with much of the administrative Northern District of the country (which also includes the Golan Heights and part of Menashe Heights, but not Qiryat Tiv’on).

Western Galilee (Hebrew: גליל מערבי‎, romanized: Galil Ma’aravi) is a common term referring to the western part of the Upper Galilee and its shore, and usually also the northwestern part of the Lower Galilee, mostly overlapping with Acre sub-district. Galilee Panhandle is a common term referring to the “panhandle” in the east that extends to the north, where Lebanon is to the west, and includes Hula Valley and Ramot Naftali mountains of the Upper Galilee.

Historically, the part of Southern Lebanon south of the east-west section of the Litani River also belonged to the region of Galilee, but the present article mainly deals with the Israeli part of the region.
