Happiness Road (Con đường Hạnh Phúc) is the popular name for the mountain road corridor that links Hà Giang City with the Đồng Văn Karst Plateau area in northern Vietnam, including Quản Bạ, Yên Minh, Đồng Văn, and Mèo Vạc. Built between 1959 and 1965, the road is commonly identified with the modern alignment of National Highway 4C across the plateau. The name is associated with Ho Chi Minh, who referred to the project as the "Happiness Road" in 1961.

The corridor includes the cliffside segment over Mã Pí Lèng Pass, above the Nho Quế River gorge and the Tú Sản canyon. The surrounding plateau forms part of the UNESCO Global Geoparks network.
