Brooke County is a county in the Northern Panhandle of the U.S. state of West Virginia. As of the 2020 census, the population was 22,559. Its county seat is Wellsburg. The county was created in 1797 from part of Ohio County and named in honor of Robert Brooke, Governor of Virginia from 1794 to 1796. Brooke County is part of the Weirton-Steubenville, WV-OH Metropolitan Statistical Area, which is also included in the Pittsburgh-New Castle-Weirton, PA-WV-OH Combined Statistical Area.

The Ohio Company of Virginia petitioned the British King for 500,000 acres of land in the Ohio River Valley in 1747, but the first settlers to this area, in what later became known as West Virginia's Northern Panhandle, were brothers Jonathan, Israel and Friend Cox. They staked a "tomahawk claim" to 1200 acres (400 acres for each brother) at the mouth of Buffalo Creek and extending along the Ohio River. Their cousin George Cox staked an adjacent claim a few years later.

In 1788 Charles Prather purchased 481 acres from Friend Cox's heir, John Cox; by that year's end Alexander Wells, formerly of Baltimore, Maryland and later of Cross Creek Township, Pennsylvania, established a trading post (together with his Baltimore cousin Richard Owings). In 1791 the Ohio County Court incorporated the town around the post as "Charlestown" (after Prather's first name). On November 30, 1796, the Virginia General Assembly formed Brooke County, from parts of Ohio County, and designated "Charlestown" as the county seat. Across the Appalachian Continental Divide to the east in Jefferson County, another Charlestown had previously been incorporated (it is now known as Charles Town). In addition, Charleston had been established at the confluence of the Elk and Kanawha rivers in 1788.

Addressing this confusion, the Virginia General Assembly on December 28, 1816, changed the Brooke county seat's name from "Charlestown" to Wellsburg, supposedly to honor Charles Wells, Prather's son-in-law. The first Masonic Lodge west of the Allegheny Mountains was established in Wellsburg on March 4, 1799. It was under the jurisdiction of the Grand Lodge of Pennsylvania for six years, but since December 17, 1817, it has been under the jurisdiction of the Grand Lodge of Virginia and later of West Virginia.

The first glass factory in Wellsburg was built in 1813, taking advantage of the relatively easy transportation on the Ohio River. When the National Road was built about five years later, its first crossing of the Ohio River was via a ferry further west. In 1818 Alexander Campbell founded the first Virginia school west of the Appalachians, which the Virginia General Assembly chartered in 1840 as Bethany College.

During the American Civil War, Brooke County's elected officials helped found the new state of West Virginia, after their efforts to block secession failed at the Virginia Secession Convention of 1861. Wellsburg received a new charter in 1866 from the newly established West Virginia legislature, and Samuel Marks became Wellsburg's first elected mayor.

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. Brooke County was divided into three districts: Buffalo, Cross Creek, and Wellsburg. Wellsburg District was co-extensive with the city of Wellsburg. The districts of Follansbee and Weirton were created between 1970 and 1980. Buffalo and Cross Creek Districts were discontinued in 2008.

According to the United States Census Bureau, the county has a total area of 93 square miles (240 km), of which 89 square miles (230 km) is land and 3.4 square miles (8.8 km) (3.6%) is water. It is the second-smallest county in West Virginia by area. The highest point of elevation in Brooke County is approximately 1372 ft. and located about 1.5 miles south of Franklin.

Brooke County is part of the First Judicial Circuit of West Virginia, which also includes Hancock and Ohio counties. In West Virginia, Circuit Judges are elected in non-partisan elections to eight-year terms. The current judges of the First Judicial Circuit are the Hon. Jason A. Cuomo, the Hon. James Mazzone, the Hon. David J. Sims, and the Hon. Ronald E. Wilson. All four Circuit Court judges were re-elected in November 2016.

Brooke County is part of the First Family Court Circuit of West Virginia which also includes Hancock and Ohio Counties. In West Virginia, Family Court Judges were first elected to six-year terms beginning in 2002 and were elected to eight-year terms beginning in 2008. The current judges of the First Family Court Circuit are the Hon. Joyce Chernenko and the Hon. William Sinclair who were both elected to eight-year terms in November 2008.

Magistrates are elected in partisan elections serving four-year terms. Vacancies occurring in unexpired terms can be filled by a respective Circuit Court Judge. Unlike Circuit Court judges or Family Court judges, magistrates are not required to be attorneys. Brooke County currently has two magistrates: Robin Snyder and Danielle Diserio.

Abutting free states Ohio and Pennsylvania, and with a largely German-American culture unlike any other part of antebellum Virginia, Brooke County and the rest of the Northern Panhandle were central to the vanguard who made West Virginia a new state during the Civil War. For the next six and a half decades the county, aided by its association with Pennsylvania's powerful ironmonger-led Republican machines, voted solidly Republican to the point of supporting William Howard Taft during the disastrously divided 1912 election. From the New Deal until Bill Clinton, however, powerful unionization meant that Brooke County turned from solidly Republican to solidly Democratic except when the Democrats nominated the liberal George McGovern in 1972. Like all of West Virginia, since 2000 a combination of declining unionization and differences with the Democratic Party's liberal views on social issues has produced a dramatic swing to the Republican Party.
