The 17 July Revolution was a bloodless coup in Iraq in 1968 led by Ahmed Hassan al-Bakr, Abd ar-Razzaq an-Naif, and Abd ar-Rahman al-Dawud that ousted President Abdul Rahman Arif and Prime Minister Tahir Yahya and brought the Iraqi Regional Branch of the Arab Socialist Ba'ath Party to power. Ba'athists involved in the coup as well as the subsequent purge of the moderate faction led by Naif included Hardan al-Tikriti, Salih Mahdi Ammash, and Saddam Hussein, the future President of Iraq. The coup was primarily directed against Yahya, an outspoken Nasserist who exploited the political crisis created by the June 1967 Six-Day War to push Arif's moderate government to nationalize the Western-owned Iraq Petroleum Company (IPC) in order to use Iraq's "oil as a weapon in the battle against Israel." Full nationalization of the IPC did not occur until 1972, under the Ba'athist administration. In the aftermath of the coup, the new Iraqi government consolidated power by denouncing alleged American and Israeli machinations, publicly executing 14 people including 9 Iraqi Jews on fabricated espionage charges amidst a broader purge, and working to expand Iraq's traditionally close relations with the Soviet Union.

The Ba'ath Party ruled from the 17 July Revolution until 2003, when it was removed from power by an invasion led by American and British forces. The 17 July Revolution is not to be confused with the 14 July Revolution, a coup on 14 July 1958, when King Faisal II was overthrown, ending the Hashemite dynasty in Iraq and establishing the Republic of Iraq, or the 8 February 1963 Ramadan Revolution that brought the Iraqi Ba'ath Party to power for the first time as part of a short-lived coalition government that held power for less than one year.
