The history of Egypt under Gamal Abdel Nasser covers the period of Egyptian history from the Egyptian Revolution of 1952, of which Gamal Abdel Nasser was one of the two principal leaders, spanning Nasser's presidency of Egypt from 1956 to his death in 1970. Nasser's tenure as Egypt's leader heralded a new period of modernisation and socialist reform in Egypt, along with a staunch advocacy of pan-Arab nationalism, and developing world solidarity. His prestige in Egypt and throughout the Arab World soared in the wake of his nationalisation of the Suez Canal Company in 1956, and Egypt's political victory in the subsequent Suez Crisis, but was damaged badly by Israel's victory in the Six-Day War.

The United Arab Republic was a sovereign state in the Middle East from 1958 until 1961. It was initially a political union between Egypt and Syria from 1958 until Syria seceded from the union following the 1961 Syrian coup d'état. Egypt continued to be known officially as the United Arab Republic until September 1971 when it was formally dissolved by Anwar Sadat.
