The 2018 United States Senate election in West Virginia took place on November 6, 2018, to elect a member of the United States Senate to represent the State of West Virginia, concurrently with other elections to the United States Senate, elections to the United States House of Representatives, and various state and local elections. Incumbent Democratic Senator Joe Manchin won re-election to a second full term against Republican Patrick Morrisey, who at the time of the 2018 elections had been West Virginia's State Attorney General since 2013. This was one of ten Democratic-held Senate seats up for election in a state won by Donald Trump in the 2016 presidential election. Morrisey conceded on election night.
Manchin was considered to be among the most vulnerable Democratic senators facing re-election in 2018 due to the state's deepening partisan lean and his declining popularity. He ultimately won a second full term, though by a much narrower margin of 3.33% compared to his 2012 landslide, losing 28 counties he won in 2012 and outperforming the margins of defeat from both Barack Obama in 2012 and Hillary Clinton in 2016 by more than 40%.
As of 2026, this is the last time that a Democrat won a congressional or statewide election in West Virginia, as well as the only general election defeat of Morrisey's career, and the last U.S. Senate race in West Virginia that was decided by a single-digit margin. Following his defeat in this election, Morrisey continued to serve as West Virginia's state attorney general until he won the 2024 West Virginia gubernatorial election and took office as the state's governor on January 13, 2025.
