Ahmed Abdel Hadi Chalabi (Arabic: أحمد الجلبي‎) (born October 30, 1944) was interim oil minister in Iraq in April-May 2005 and December-January 2006 and deputy prime minister from May 2005 until May 2006. Chalabi failed to win a seat in parliament in the December 2005 elections, and when the new Iraqi cabinet was announced in May 2006, he was not awarded a post. Once dubbed the "George Washington of Iraq" he has fallen out of favor and is currently under investigation by several U.S. government sources. Chalabi was also part of a three-man executive council for the umbrella Iraqi opposition group, the Iraqi National Congress (INC), created in 1992 for the purpose of fomenting the overthrow of Iraqi president Saddam Hussein. Although the INC received major funding and assistance from the United States, it never had any influence or any following to speak of in Iraq after the 2003 invasion. The INC's influence gradually waned until the December 2005 elections, in which it failed to win a single seat in Parliament.

Chalabi is a controversial figure for many reasons. In the lead-up to the 2003 invasion of Iraq, under his guidance the INC, with the assistance of lobbying powerhouse BKSH & Associates, provided a major portion of the information on which U.S. Intelligence based its condemnation of Saddam Hussein, including reports of weapons of mass destruction and alleged ties to al-Qaeda. Nearly all, if not all, of this information has turned out to be of questionable accuracy. That, combined with the fact that Chalabi subsequently boasted about the impact that their alleged falsifications in an interview with the British Sunday Telegraph, led to a falling out between him and the United States.

Initially, Chalabi enjoyed close political and business relationships with some members of the U.S. government, including some prominent neoconservatives within the Pentagon. Chalabi is said to have had political contacts within the Project for the New American Century, most notably with Paul Wolfowitz, a student of nuclear strategist Albert Wohlstetter, and Richard Perle who was introduced to Chalabi by Wohlstetter in 1985. He also enjoyed considerable support among politicians and political pundits in the United States, most notably Jim Hoagland of The Washington Post, who held him up as a notable force for democracy in Iraq. He was a special guest of First Lady Laura Bush at the 2004 State of the Union Address.
