Route 72, commonly known as Kalanianaʻole Highway, is the main highway serving southeast Oʻahu. Beginning at the eastern terminus of Interstate H-1 (H-1), the east–west highway travels along the southeastern shore of Oʻahu through various residential neighborhoods, including Hawaiʻi Kai. It turns northwest at Makapuʻu and runs through Waimānalo before terminating in Maunawili at an intersection with Kamehameha Highway and Pali Highway. The highway is named for Jonah Kūhiō Kalanianaʻole, a former prince of the Kingdom of Hawaiʻi.

Route 72 begins as an extension of Interstate H-1 (the Lunalilo Freeway), near the Kahala Mall in eastern Honolulu. The six-lane road travels east through a residential neighborhood along the north side of the Waialae Country Club towards the Pacific Coast. At Wailupe Beach, it turns northeast and continues along the coast through ʻĀina Haina, crossing several streams and suburban lagoons.^[1]

The highway turns southeast near Hawaiʻi Kai, crossing the inland waters of the Kui Channel and climbing part of Koko Crater.

The highway was named for Jonah Kūhiō Kalanianaʻole, a Hawaiian prince and later Congressman who attempted to restore Queen Liliʻuokalani to the throne after the 1893 overthrow by American residents.^[2]

The entire route is in Honolulu County.
