The Glady Fork is a river, approximately 30 miles (48 km) long, in eastern West Virginia in the United States. It is a tributary of the Dry Fork; via the Dry Fork, the Black Fork, and the Cheat, Monongahela and Ohio Rivers, it is part of the watershed of the Mississippi River, draining an area of 64 square miles (166 km²) in the Allegheny Mountains. With the Dry Fork, the Laurel Fork, the Shavers Fork and the Blackwater River, it is considered to be one of the five principal headwaters tributaries of the Cheat River.[8] The stream was named for the presence of glades along the river.[9]
