Nicholas Valentino Lampson (born February 14, 1945) is an American politician who represented Texas's 22nd congressional district from 2007 to 2009 and Texas's 9th congressional district before that from 1997 to 2005.

Lampson was born on February 14, 1945, in Beaumont, Texas, one of six children. His grandparents came to the United States from Italy and settled in Stafford, Texas, where they owned farms and were founding members of their church. His parents grew up, met, and married in Fort Bend County. Lampson's mother and father eventually moved to Beaumont, where he was born.

Lampson is one of six children born to a welder and a homemaker. His father died when he was 12 years old, and Lampson took his first job at that young age sweeping floors to supplement the family's income. Lampson's mother received $19 per month from Social Security as long as he stayed in school. This money helped his family stay together in those difficult years. This would later influence his commitment to protecting Social Security.

Though Lampson's mother had only a fifth grade education, she encouraged her children in school, and all six graduated from college with at least one degree. His mother earned her GED on her 80th birthday. Lampson earned a Bachelor of Science degree in biology and a master's degree in education from Lamar University, where he was a member of the Pi Kappa Alpha fraternity. He taught high school science at Hebert High School in Beaumont. An inner calling to be of service to others, and the experience of interning with Congressman Jack Brooks in 1969, led him to seek public office.

In 1976, Lampson was elected tax assessor-collector for Jefferson County and served nearly twenty years. He instituted an emphasis on customer service, successfully pushed for major upgrades in computer technology, and reduced the cost of collecting taxes by $3 million a year.

He resigned from his post in order to run for congress.

In the 1996 election, Lampson decided to run for a seat in the U.S. House of Representatives representing Texas's 9th congressional district. The incumbent was Republican U.S. Congressman Steve Stockman, who was a freshman in congress. The district had been represented by Democrat Jack Brooks for 42 years, but Brooks had been one of the most prominent Democratic incumbents to lose re-election in the "Republican Revolution" of 1994, which brought the House under the control of Republicans for the first time since the 83rd United States Congress following the 1952 elections. Lampson won the Democratic primary with 69% of the vote. In the general election, he defeated Stockman 53%-47%.

He won re-election to a second term against Republican Tom Cottar 64%-36%.
