The West Virginia Legislature is the state legislature of the U.S. state of West Virginia. A bicameral legislative body, the legislature is split between the upper Senate and the lower House of Delegates. It was established under Article VI of the West Virginia Constitution following the state's split from Virginia during the American Civil War in 1863. As with its neighbor and former constituent Virginia General Assembly, the legislature's lower house is also referred to as a "House of Delegates."

The West Virginia Senate is the upper house of the West Virginia Legislature. There are seventeen senatorial districts. Each district has two senators who serve staggered four-year terms. Although the Democratic Party held a supermajority in the Senate as recently as 2015, Republicans now dominate in the chamber, and hold 31 seats to the Democrats' three seats.
