Farrington Highway is a major highway through the western part of O‘ahu in the U.S. state of Hawaii. Starting from Kamehameha Highway north of Pearl Harbor, it heads west along the island's southwestern and western coast; another part of the highway also serves the western part of the North Shore, ending in Waialua. With the exception of a gap around Kaena Point which is no longer passable to cars, the highway forms an almost continuous arc along the coast of the western half of the island of O‘ahu.

The route that is now Farrington Highway began as a walking route for those who accessed Waianae and Makaha area from central Oahu and the Ewa Beach area.
