Kamehameha Highway is one of the main highways serving suburban and rural O‘ahu in the U.S. state of Hawai‘i. Informally known as Kam Highway, it begins at Nimitz Highway near Pearl Harbor and Hickam Air Force Base in Honolulu, serves the island's older western suburbs, and turns north across the O‘ahu Central Valley to the North Shore. At the North Shore, Kamehameha Highway heads northeast around the northern tip of O‘ahu, then southeast to and just beyond Kāne‘ohe Bay on the windward coast. The road was named after King Kamehameha I.
