| Elections in West Virginia |

 |
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. This was one of ten Democratic-held Senate seats up for election in a state won by Donald Trump in the 2016 presidential election.
Incumbent Senator Joe 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. Manchin ultimately won a second full term, though by a much narrower margin of 3.33% compared to his 2012 landslide. Manchin outperformed the margins of defeat from both Hillary Clinton in 2016 and Joe Biden in 2020 by more than 40 percentage points.
As of 2024, this is the last time that a Democrat won a congressional and/or non-judicial statewide election in West Virginia.
