Conor James Lamb (born June 27, 1984) is an American attorney and politician who served as the U.S. representative for Pennsylvania's 17th congressional district from 2018 to 2023. A member of the Democratic Party, he previously represented the neighboring 18th district in 2018. Lamb was also an unsuccessful candidate in the 2022 United States Senate election in Pennsylvania. A longtime resident of Pittsburgh, Lamb earned his Juris Doctor degree from the University of Pennsylvania and served as an assistant U.S. attorney in his home city from 2014 to 2017. He ran for the 18th district's seat in a special election caused by Republican Congressman Tim Murphy's resignation and defeated Republican Rick Saccone. After Pennsylvania's congressional map was redrawn by court order the same year, Lamb won his first full term to the 17th district in the general election. Lamb did not seek re-election to his House seat in 2022, choosing instead to run for Senate. He finished second in the Democratic primary behind John Fetterman.
