Monongalia County is included in the Morgantown, WV Metropolitan Statistical Area, and is the largest county in North-Central West Virginia. It is part of the Pittsburgh media market.
History
Monongalia County takes its name from the Monongahela River. The name Monongalia may be a misspelling of Monongahela. Alternatively, the conventional Latinate ending "-ia" (designating "land of..." or "country of..." — as in Arabia, Bolivia or Colombia) may have been added to Monongahela (i.e., "Land of the Monongahela").
Monongalia County was formed in 1776 when Virginia's remote District of West Augusta was divided into three counties: Ohio, Yohogania and Monongalia, all named for their most prominent rivers. Ohio County then encompassed most of the western region of the district bordering the Ohio River, including parts of what is now southwestern Pennsylvania. Yohogania County consisted of much of what is now southwestern Pennsylvania and the present counties of Hancock and the northern part of Brooke in West Virginia. Monongalia County also encompassed what are now the counties of Tucker, Randolph, Harrison and Barbour in north-central West Virginia, as well as parts of what are now Washington, Greene and Fayette Counties in Pennsylvania. In 1780, in his Notes on the State of Virginia, Thomas Jefferson gave the militia enrollment of what was then the vast Monongalia County at 1,000 troops.
In 1863, 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. Monongalia County was divided into seven districts: Battelle, Cass, Clay, Clinton, Grant, Morgan, and Union. After a century of relative stability, in the 1970s Monongalia's seven historic magisterial districts were consolidated into three new Districts: Central, Eastern, and Western.

Government and politics
The county government consists of a county commission with three members. Currently, these members are: Thomas Bloom (D), Sean Sikora (R) and Jeffery Arnett (D).
In the 20th century, Monongalia County had been a bellwether for West Virginia, voting the same as the state in every election from 1916 to 2020, even as the candidate lost the national election, with the sole exception of 2008 when Barack Obama won the county and lost the state. While still typically favoring Republicans, the county tends to lean significantly more Democratic than the rest of West Virginia. Donald Trump carried the county with just over 500 more votes than Democrat Joe Biden in the 2020 presidential election, by far Biden's best county-level performance in the state.
Education
The county's public schools are operated by Monongalia County Schools. The county is also home to West Virginia's largest university, West Virginia University, located in Morgantown.
