The Authorization for Use of Military Force Against Iraq Resolution of 2002, informally known as the Iraq Resolution, is a joint resolution passed by the United States Congress in October 2002 as Public Law No. 107-243, authorizing the use of the United States Armed Forces against Saddam Hussein's Iraq government in what would be known as Operation Iraqi Freedom.

The resolution cited many factors as justifying the use of military force against Iraq:

The resolution "supported" and "encouraged" diplomatic efforts by President George W. Bush to "strictly enforce through the U.N. Security Council all relevant Security Council resolutions regarding Iraq" and "obtain prompt and decisive action by the Security Council to ensure that Iraq abandons its strategy of delay, evasion, and noncompliance and promptly and strictly complies with all relevant Security Council resolutions regarding Iraq."

The resolution authorized President Bush to use the Armed Forces of the United States "as he determines to be necessary and appropriate" in order to "defend the national security of the United States against the continuing threat posed by Iraq; and enforce all relevant United Nations Security Council Resolutions regarding Iraq."

An authorization by Congress was sought by President George W. Bush soon after his September 12, 2002 statement before the U.N. General Assembly asking for quick action by the Security Council in enforcing the resolutions against Iraq.

Of the legislation introduced by Congress in response to President Bush's requests, S.J.Res. 45 sponsored by Sen. Daschle and Sen. Lott was based on the original White House proposal authorizing the use of force in Iraq, H.J.Res. 114 sponsored by Rep. Hastert and Rep. Gephardt and the substantially similar S.J.Res. 46 sponsored by Sen. Lieberman were modified proposals. H.J.Res. 110 sponsored by Rep. Hastings was a separate proposal never considered on the floor. Eventually, the Hastert–Gephardt proposal became the legislation Congress focused on.

Introduced in Congress on October 2, 2002, in conjunction with the Administration's proposals, H.J.Res. 114 passed the House of Representatives on Thursday afternoon at 3:05 p.m. EDT on October 10, 2002, by a vote of 296–133, and passed the Senate after midnight early Friday morning, at 12:50 a.m. EDT on October 11, 2002, by a vote of 77–23. It was signed into law as Pub. L. 107–243 (text) (PDF) by President Bush on October 16, 2002.
