This page is subject to the extended confirmed restriction related to the Arab-Israeli conflict.Hill 777 or Givat Arnon (Hebrew: גבעת ארנון) is an Israeli outpost in the West Bank, a 12-kilometer drive from Itamar, under the jurisdiction of the Shomron Regional Council, 28 km inside the Green Line.

[5] The name Givat Arnon was given in memory of Aryeh Agranioni.

In May 2001, Agranioni was guarding a railway container housing agricultural equipment on Hill 777.

The murder of Agranioni helped accelerate the issuing of a military permit enabling the Hill 777 outpost.

Residents returned home to Hill 777 only one year after leaving.
