Honolulu (; Hawaiian: [honoˈlulu]) is the capital and largest city of the U.S. state of Hawaii. It is an unincorporated part of and the county seat of the City and County of Honolulu along the southeast coast of the island of Oʻahu. The city is the main gateway to Hawaiʻi and a major portal into the United States. The city is also a major hub for international business, military defense, as well as famously being host to a diverse variety of east-west and Pacific culture, cuisine, and traditions.
Honolulu is the most remote city of its size in the world, and is the westernmost and southernmost major U.S. city. For statistical purposes, the United States Census Bureau recognizes the approximate area commonly referred to as "City of Honolulu" (not to be confused with the "City and County") as a census county division (CCD). Honolulu is a major financial center of the islands and of the Pacific Ocean. The population of the Honolulu census designated place (CDP) was 359,870 as of the 2017 population estimate, while the Honolulu CCD was 390,738 and the population of the consolidated city and county was 953,207.
Honolulu means "sheltered harbor" or "calm port". The old name is Kou, a district roughly encompassing the area from Nuʻuanu Avenue to Alakea Street and from Hotel Street to Queen Street which is the heart of the present downtown district. The city has been the capital of the Hawaiian Islands since 1845 and gained historical recognition following the attack on Pearl Harbor by Japan near the city on December 7, 1941.
As of 2015, Honolulu was ranked high on world livability rankings, and was also ranked as the 2nd safest city in the U.S. It is also the most populated Oceanian city outside Australasia and ranks second to Auckland as the most-populous city in Polynesia.
