Duncan Lee Hunter (born May 31, 1948) is an American politician. He was a Republican member of the House of Representatives from California's 52nd, 45th and 42nd districts from 1981 to 2009. Hunter was the chairman of the House Armed Services Committee during the 108th and 109th Congress. Hunter sought the Republican Party nomination for President of the United States for 2008, but his campaign failed to attract significant voters or delegates in early primary and caucus states, and he dropped out after the Nevada Republican caucuses.

On December 8, 2006, Hunter introduced H.R. 6375, which would have required the defense department to post the purpose of all congressional earmarks in annual defense bills, along with the location and a grade according to the utility of the earmark.  Hunter introduced H.R. 552, The Right to Life Act, on February 2, 2005. The purpose of the bill is to "implement equal protection... for the right to life of each born and preborn human person." In the 109th Congress, the legislation collected 101 cosponsors. Hunter states that The Right to Life Act "would legally define "personhood" as the moment of conception and, therefore, guarantee all constitutional rights and protections, including life, to the unborn without utilizing a constitutional amendment." Hearings for H.R. 552 were scheduled for December 12, 2006, but were cancelled right before the House adjourned.  On April 28, 2004, Hunter introduced legislation that he said could "turn parents into prosecuting attorneys fighting a wave of obscenity." HR 6390 IH, also called the "Parents Empowerment Act", would allow the parent or guardian of a minor to sue in federal court anyone who knowingly disseminates material "that is harmful to minors", or specifically, "any pornographic communication, picture, image, graphic image file, article, recording, writing, or other pornographic matter of any kind", if it is distributed in a way that "a reasonable person can expect a substantial number of minors to be exposed to the material and the minor, as a result to exposure to the material, is likely to suffer personal or emotional injury or injury to mental or moral welfare."  In 1994, Hunter legislatively mandated the construction of 14 miles (23 km) of security fencing on the international land border separating San Diego County and Tijuana, Mexico. In 2005, Hunter introduced legislation calling for the construction of a reinforced fence along the entire U.S.-Mexico border, citing crime statistics as measures of San Diego-Tijuana fence's success. After successfully adding an amendment to a House-passed bill that ultimately stalled in House-Senate negotiations, Hunter's amendment was later incorporated into H.R. 6061, the Secure Fence Act, introduced by New York Congressman Peter T. King. He has said that if he becomes President, the 754-mile (1,213 km) double layer border fence will be built in less than 12 months.  Hunter repeatedly voted against international trade agreements such as the North American Free Trade Agreement (NAFTA), the Central America Free Trade Agreement (CAFTA) and the World Trade Organization (WTO).
