Stanleyville is an unincorporated community between northern Winston-Salem and Rural Hall in Forsyth County, North Carolina, United States. Most of the community has been annexed by Winston-Salem. Stanleyville is located along North Carolina Highway 66 (NC 66) near the NC 74 interchange with U.S. Route 52 (US 52). It is home to many farms and recently has seen a surge in commercial expansion. It does not have a post office, so all mail is routed through adjoining Rural Hall.
