Union is a town in Monroe County, West Virginia, United States.

However, shortly after Monroe County was created, James Alexander offered 25 acres of land, including a lot for a courthouse which in time became the town of Union.

[6] By 1810, at least sixteen lots had been sold in the newly laid out town of Union and a courthouse and jail were built at its center.

Little activity during the American Civil War occurred around Union other than troop movements, especially in 1864 when regiments of the U.S. Army under General Crook encamped near the town.

A majority of the citizens of Union supported the Confederacy and opposed the creation of West Virginia which included Monroe County.

[7] The town of Union retains much of its historic architecture, with many structures dating to the antebellum period when the local economy was thriving from the resort industry.

The present Monroe County Courthouse, built in 1881, displays the fashionable Romanesque style of the late-19th century.

The Monroe County Historical Society preserves several historic structures in the town, including the Caperton Law Office, Owen Neel House, Clark-Wisemen House, Ames Clair Hall, and the Old Baptist Church.

[10] According to the United States Census Bureau, the town has a total area of 0.45 square miles (1.17 km2), all land.
