The Allon Plan (Hebrew: תָּכְנִית אַלּוֹן) was a political proposition that outlined potential next steps for Israel after the 1967 Arab–Israeli War. It was drafted by Israeli politician Yigal Allon following Israel's seizure of territory from Syria, Jordan, and Egypt; the Israeli military had come to occupy Syria's Golan Heights, the Jordanian-annexed West Bank and the Egyptian-occupied Gaza Strip, and Egypt's Sinai Peninsula. Allon advocated a partitioning of the West Bank between Israel and Jordan, the creation of a sovereign state for Druze in the Golan Heights, and the return of most of the Sinai Peninsula to Egypt.

Broader aims of the Allon Plan in partitioning the West Bank were to enable an Israeli annexation of East Jerusalem, the Etzion Bloc, and most of the Jordan Valley (from the Jordan River to the eastern slopes of the hill ridge). All remaining parts of the West Bank, containing the majority of Palestinians, were to be returned to Jordan — connected to the country by a corridor through Jericho — or reorganized as Palestinian autonomous territory. However, the Allon Plan was rejected by Jordanian king Hussein.

Allon died in 1980 and his proposition was never implemented, though the Sinai Peninsula had been returned as part of the Egypt–Israel peace treaty in 1979. In 1981, the Israeli government passed the Golan Heights Law, effectively annexing the territory captured from Syria.
