The Bacolod South Road, also known as Negros South Road, is a 212.59-kilometer (132.10 mi), two-to-six lane major north–south lateral highway that connects the city of Bacolod[1] to the municipality of Hinoba-an[2] in the province of Negros Occidental,[3][4] Philippines.

It continues its course along the western coast of Negros Occidental as it traverses Pulupandan, Valladolid, San Enrique, Pontevedra, Hinigaran, Binalbagan, Himamaylan, and Kabankalan, wherein from barangay Binicuil it is locally known as Guanzon Street.

Shortly, it turns to the northeast locally known as Justice Y. Perez Avenue and continues its course along the western and southern coast of Negros Occidental.

It terminates in Hinoba-an, near the provincial boundary with Negros Oriental, where it is continued by Dumaguete South Road.

After the World War II, the road was extended from its former southern terminius in Sojoton Point in Cauayan to Hinoba-an.
