Charles Spittal "Chuck" Robb (born June 26, American politician. Robb, a Democrat, served as governor of Virginia from 1982 to 1986 and later as a member of the U.S. Senate from 1989 until 2001. Robb's wife, Lynda Robb, also known as Lynda Bird Johnson, is the daughter of former U.S. President, and fellow southern Democrat, Lyndon B. Johnson.

On April 25, 1991, Robb preempted NBC's plans to break a sex scandal story by publicly admitting that he had spent time with former Miss Virginia Tai Collins alone in a hotel room. Robb claimed that the two had merely shared a bottle of wine and a massage. However, Collins later told Playboy magazine that the two had been having an affair since 1983.

Despite the sex scandal, Robb narrowly defeated former Iran-Contra figure Oliver North in a 1994 reelection bid after popular Republican Senator John Warner refused to support his fellow Republican and instead backed third-party candidate J. Marshall Coleman. After two terms in the Senate, he was defeated in the 2000 election by his Republican opponent, George Allen, who was also a former governor. Robb was the only Democratic incumbent senator to be defeated in that election. After losing to Allen, Robb began teaching at George Mason University law school.

On February 6, 2004, Robb was appointed co-chair of the Iraq Intelligence Commission, an independent panel tasked with investigating U.S. intelligence surrounding the United States' 2003 invasion of Iraq and Iraq's weapons of mass destruction.
