Fort Gay is a town in Wayne County, West Virginia, United States, situated along the Tug Fork and Big Sandy rivers.

[3] The Fort Gay community traces back to 1789, when 11 people established a settlement at the junction of the Tug and Big Sandy rivers, across from what is now Louisa, Kentucky.

Although there is no evidence as to why the name was changed, there are several prevalent theories: that either the railroad company or post office did not want two Cassvilles on the same route/state (there is another Cassville, West Virginia), or that a Civil War nurse named Gay became synonymous with the town.

The Norfolk Southern Railway's Kenova District goes through the western edge of town.

Microsoft customer service representatives refused to acknowledge that Fort Gay existed, and it took an appeal from Mayor David Thompson and media coverage for the issue to be corrected.
