United Nations Security Council Resolution 1441 is a United Nations Security Council resolution adopted unanimously by the United Nations Security Council on 8 November 2002, offering Iraq under Saddam Hussein "a final opportunity to comply with its disarmament obligations" that had been set out in several previous resolutions (Resolutions 660, 661, 678, 686, 687, 688, 707, 715, 986, and 1284). It provided a justification for the subsequent US invasion of Iraq.Resolution 1441 stated that Iraq was in material breach of the ceasefire terms presented under the terms of Resolution 687. Iraq's breaches related not only to weapons of mass destruction (WMD), but also the known construction of prohibited types of missiles, the purchase and import of prohibited armaments, and the continuing refusal of Iraq to compensate Kuwait for the widespread looting conducted by its troops during the 19901991 invasion and occupation. It also stated that "...false statements or omissions in the declarations submitted by Iraq pursuant to this resolution and failure by Iraq at any time to comply with, and cooperate fully in the implementation of, this resolution shall constitute a further material breach of Iraq's obligations."

The Iraq disarmament crisis was claimed as one of primary issues that led to the multinational invasion of Iraq on 20 March 2003. Since the 1980s, Iraq was widely assumed to have been producing and extensively running the programs of biological, chemical and nuclear weapons. Iraq made extensive use of chemical weapons during the Iran–Iraq War in the 1980s, including against its own Kurdish population. France and the Soviet Union assisted Iraq in the development of its nuclear program, but its primary facility was destroyed by Israel in 1981 in a surprise air strike.

After the Gulf War in 1990, the United Nations located and destroyed large quantities of Iraqi chemical weapons and related equipment and materials with varying degrees of Iraqi cooperation and obstruction, but the Iraqi cooperation later diminished in 1998. The disarmament issue remained tense throughout the 1990s with U.S. at the UN, repeatedly demanding Iraq to allow inspections teams to its facilities. These crises reached their climax in 2002-2003, when U.S. President George W. Bush demanded a complete end to what he alleged was Iraqi production of weapons of mass destruction, and reasoned with Iraqi President Saddam Hussein to comply with UN Resolutions requiring UN weapons inspectors unfettered access to areas those inspectors thought might have weapons production facilities.

Since the Gulf War in 1991, Iraq had been restricted by the United Nations (UN) from developing or possessing such weapons. It was also required to permit inspections to confirm Iraqi compliance. Bush repeatedly backed demands for unfettered inspection and disarmament with threats of invasion. On 20 March 2003, a multinational alliance containing the armed forces of the United States and United Kingdom launched an invasion of Iraq in 2003. After the withdrawal of U.S. troops from Iraq in 2011, a number of failed Iraqi peace initiatives were revealed.
