The Authorization for Use of Military Force Against Iraq Resolution of 2002, commonly known as the Iraq Resolution, is a U.S. congressional joint resolution (Public Law 107-243) enacted in October 2002 that authorized President George W. Bush to use the U.S. Armed Forces as necessary to defend national security against the continuing threat posed by Iraq and to enforce relevant United Nations Security Council resolutions regarding Iraq. Passed on October 16, 2002, the resolution cited Iraq's alleged possession of weapons of mass destruction, support for terrorism, and failure to comply with UN Security Council resolutions as justifications, and it referenced the Iraq Liberation Act of 1998 as foundational policy. This legislation paved the way for the 2003 invasion of Iraq, known as Operation Iraqi Freedom, which aimed to remove Saddam Hussein's regime.

Introduced as H.J.Res. 114 in the 107th Congress, it passed the House of Representatives on October 10, 2002, by a vote of 296-133, and the Senate on October 11, 2002, by 77-23, before being signed into law by President Bush on October 16, 2002. The measure has been highly controversial, with critics arguing it unconstitutionally delegated war powers to the executive branch and was based on flawed intelligence regarding Iraq's weapons programs. Over the years, it has been invoked to justify ongoing U.S. military operations in the region, leading to efforts in Congress to repeal it. In 2023, the House of Representatives voted to repeal the 2002 AUMF, highlighting concerns over its role in enabling 'endless wars,' though the Senate's action on related authorizations has also been noted.

As a key piece of legislation in U.S. foreign policy, the Iraq Resolution remains a focal point for debates on congressional war powers, executive authority, and the long-term implications of military interventions. It underscores tensions between legislative oversight and presidential discretion in matters of national security, influencing subsequent authorizations for military force.
