Wood County is a county in the U.S. state of West Virginia. As of the 2020 census, the population was 84,296, making it West Virginia's fifth-most populous county. Its county seat is Parkersburg. The county was formed in 1798 from the western part of Harrison County and named for James Wood, governor of Virginia from 1796 to 1799.

Wood County is part of the Parkersburg-Vienna, WV Metropolitan Statistical Area.

Wood County was formed on December 21, 1798, from portions of Harrison County. It was named for the then Governor of Virginia (1796–99), James Wood, formerly a brigadier general in the American Revolutionary War.

In 1861, Virginia seceded from the Union. The delegates of the 40 western counties who opposed secession formed their own government and seceded from the Confederate state of Virginia. West Virginia was granted statehood in 1863.

Later that year, West Virginia's counties were divided into civil townships, with the intention of encouraging local government. This proved impractical in the heavily rural state, and in 1872 the townships were converted into magisterial districts. Wood County was divided into ten districts: Clay, Harris, Lubeck, Parkersburg, Slate, Steele, Tygart, Union, Walker, and Williams.

According to the United States Census Bureau, the county has a total area of 377 square miles (980 km), of which 366 square miles (950 km) is land and 11 square miles (28 km) (2.8%) is water.

Wood County's northern and western boundary is the Ohio River. The Little Kanawha River flows northwestward through the county to its mouth at the Ohio River in Parkersburg. Tributaries of the Little Kanawha River in Wood County include Worthington Creek, Tygart Creek, and Walker Creek.
