Honolulu Harbor, also called Kulolia and Ke Awa O Kou and the Port of Honolulu, is the principal seaport of Honolulu and the State of Hawaiʻi in the United States. From the harbor, the City & County of Honolulu was developed and urbanized, in an outward fashion, over the course of the modern history of the island of Oahu. It includes Matson, Inc. harbors on Sand Island.

Honolulu is the capital and most populous city of the U.S. state of Hawaii, which is in the Pacific Ocean.
