Former State Route 8A (SR 8A) was a two-part state highway in the U.S. state of Nevada, running from California State Route 299 in a general easterly and southeasterly direction via Vya and Denio to US 95 north of Winnemucca, and south from US 40 at Battle Mountain via Austin to US 6 near Tonopah. It was a branch of State Route 8, which followed US 95 north from US 40 at Winnemucca to Oregon. The part northwest from US 95 towards the Oregon state line later became State Route 140, part of the Winnemucca to the Sea Highway.
