Marion County is a county in the U.S. state of West Virginia. As of the 2020 census, the population was 56,205 and its county seat is Fairmont. The county was named in honor of General Francis Marion (ca. 1732–1795), known to history as "The Swamp Fox". Marion County comprises the Fairmont, WV Micropolitan Statistical Area, which is part of the larger Morgantown–Fairmont, WV Combined Statistical Area.

History

The Adena and successor Hopewell cultures flourished in the area at one time. The region which includes the land now known as Marion County was sparsely occupied by Native Americans, if at all, in the late 18th century. Like much of the Ohio Valley, it had been depopulated by the Iroquois during the later Beaver Wars (1670–1700). Only a few abortive attempts to start European settlements on the Monongahela River or its branches (including one which gave its name to Dunkard Creek) are known prior to the French and Indian War. It was not until 1772 that any permanent settlements were made in this region.

Marion County was created by an act of the Virginia Assembly on January 14, 1842, from parts of Monongalia and Harrison counties. It was named after General Francis Marion, of American Revolutionary War fame, known to history as "The Swamp Fox".

Starting with the great flood on Monday, April 5, 1852 was an eventful year in Marion County's history. Heavy rains the day before caused the Monongahela and West Fork Rivers to rise at rate of 5 feet per hour until Tuesday afternoon, when the water reached 43 feet above its normal level. The greatest damage was sustained on the West Fork, where over 40 houses and buildings were swept away and floated past Fairmont. The flood damaged the railroad, which was in the final stages of being completed. By June 23 the Baltimore and Ohio Railroad was completed, connecting Fairmont to the west and to large cities in the east like Baltimore. The railroad required the building of a bridge to cross the Monongahela River about 1 mile west of Fairmont. That was achieved by building a massive iron bridge spanning 650 feet and lifted 35 feet above the water. Marion County was divided into seven districts: Fairmont, Grant, Lincoln, Mannington, Paw Paw, Union, and Winfield. In the 1980s, the historic magisterial districts were consolidated into three new districts: Middletown, Palatine, and West Augusta.
