Nicholas Valentino 'Nick' Lampson (born February 14, 1945) is an American politician from the state of Texas and was a Congressman representing the 22nd Congressional District of Texas. He was defeated by Pete Olson on November 4, 2008 in his re-election bid.

Lampson was a Democratic member of the U.S. House of Representatives from Texas's 9th congressional district from 1997 to 2005. After redistricting, he was the unsuccessful Democratic candidate for Texas's 2nd congressional district in 2004. After a one-term hiatus from Congress, he returned to Congress from the 22nd district, formerly represented by former Republican majority leader Tom DeLay until June 9, 2006. On November 13, 2006, Shelley Sekula-Gibbs was sworn in to serve out the remainder of DeLay's unexpired term and served approximately 51 days. She had won a special election held on the same day as the general election in which Lampson defeated her.

He is a lifelong resident of southeast Texas and a second-generation Italian-American. His grandparents came to America from Italy and settled in Stafford, Texas, nearly 100 years ago, where they had farms and were founding members of their church. His parents grew up, met, and married in Fort Bend County, and the Lampson children spent a great deal of time on their grandparents' farms working the fields.
