Giv'at Halfon Eina Ona (Hebrew: גבעת חלפון אינה עונה, lit: "Halfon Hill Doesn't Answer"), also titled Giv'at Halfon, is a cult Israeli comedy film produced in 1976. It is a good-hearted satire of the Israel Defense Forces which tells the story of a reserves company, watching the Egyptian border in Sinai. Characters such as the conman Sergio Constanza, the Egyptian-born Mr. Hasson, and the huge cook Yosifoun became classics.

The name of the film is a parody of the name of the Israeli patriotic film Giv'a 24 Eina Ona (Hill 24 Doesn't Answer).

The film was directed and co-written by Assi Dayan and stars members of HaGashash HaHiver: Shaike Levi, Yisrael Poliakov, and Gavri Banai.
