Oliver Laurence North (born October 7, 1943) is an American political commentator, television host, military historian, author, and retired United States Marine Corps lieutenant colonel.

North was a National Security Council staff member during the Iran–Contra affair, a political scandal of the late 1980s. It involved the illegal sale of weapons to the Khomeini regime of the Islamic Republic of Iran to encourage the release of American hostages then held in Lebanon. North formulated the second part of the plan, which was to divert proceeds from the arms sales to support the Contra rebel groups in Nicaragua, sales which had been specifically prohibited under the Boland Amendment. North was granted limited immunity from prosecution in exchange for testifying before Congress about the scheme. He was initially convicted on three felony charges, but the convictions were vacated and reversed and all charges against him dismissed in 1991.

North unsuccessfully ran for the U.S. Senate seat held by Chuck Robb from Virginia in 1994. In a three-way race, North narrowly lost to Robb by a margin of 2.73%. He then hosted a talk show on Radio America from 1995 to 2003 and one on Fox News from 2001 to 2016. He was also president of the National Rifle Association from 2018 to 2019.
