County in West Virginia, United States

Monroe County is a county in the U. S. state of West Virginia. As of the 2020 census, the population was 12,376. Its county seat is Union. Monroe County was the home of Andrew Summers Rowan of Spanish–American War fame, who is immortalized in Elbert Hubbard's classic A Message to Garcia. The county was also the site of the 1928 discovery of the 34.48 carat (6.896 g) Jones Diamond by Grover C. Jones and William "Punch" Jones. Monroe County celebrates its own holiday, Farmers' Day.

Monroe County was created from Greenbrier County on January 14, 1799, and was named for Virginia civic figure James Monroe, who would be elected fifth President of the United States in November 1816. It was one of fifty Virginia counties that were admitted to the Union as the state of West Virginia on June 20, 1863, at the height of the Civil War. Monroe County did not participate in the creation of the new state, but was included by Congressional decree. Almost all the men from Monroe who served in the Civil War enlisted in the Confederate army. 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. Monroe County was initially divided into seven townships: Forest Hill, Red Sulphur, Second Creek, Springfield, Sweet Springs, Union, and Wolf Creek. In 1871, part of Forest Hill Township was added to the new county of Summers, and the remaining territory distributed between Red Sulphur and Springfield Townships. The following year, the six remaining townships became magisterial districts. Except for minor adjustments, the six historic magisterial districts were unchanged until the 1990s, when they were consolidated into three new districts: Central, Eastern, and Western.

Monroe County lies on the southeast side of West Virginia. Its southeast border abuts the northwest border of the state of Virginia. The New River flows northward for a short distance along the county's southwest border. The county's terrain is mountainous and tree covered, with all sufficiently level surfaces devoted to agriculture. The terrain slopes to the north and west, with its highest part the middle part of its border with Virginia, at 3,862 feet (1177 m) ASL. The county has a total area of 474 square miles (1,228 km2), of which 473 square miles (1,225 km2) is land and 0.9 square miles (2 km2) (0.2%) is water.

The Federal Bureau of Prisons' Federal Prison Camp, Alderson was the nation's first women's federal prison. It is located in Monroe and Summers counties, west of Alderson.

One of Monroe County's geological features is Haynes Cave, a former saltpeter mine. Workers in the mine found strange bones in the cave at the end of the 18th Century, and mailed them to Thomas Jefferson. Jefferson's study of the animal, the Megalonyx jeffersonii was arguably the birth of American paleontology. It is now the official West Virginia state fossil. However, other saltpeter caves are in private ownership, and allow only limited public access due to ecological risks. One such is the Greenville Saltpeter Cave, designated a national natural landmark in 1973, and very important during the War of 1812.

Farmers' Day is an annual event, held on the first Saturday in June in Union, to recognize the farming families in the surrounding area. The event, founded by Louie H. Peters, fills the weekend, with a Friday dance, a 3k run, a Saturday pancake breakfast, Sunday activities, and a parade held in the town of Union.
