Guam's deep water port, sheltered within the inner reaches of Apra Harbor, offers facilities and services to ships of all registries. Dedicated to providing a combination of maritime, commercial, transportation, and recreational services in a safe, efficient, and reliable manner through the development of modern facilities, information technology, and skilled workforce, the Port Authority of Guam is striving to develop into the world-class container terminal port of the Western Pacific Region.


It is our objective to modernize the Port as a first class facility in the region providing cargo handling services in a safe, efficient & sustainable manner. To achieve this, the Port must increase capacity, execute infrastructure development and Port expansion to meet the community's organic growth and the impending military buildup, promote economic growth & opportunities for maritime related industries and address the needs of port users.


The Port Authority of Guam is dedicated to providing full services to ocean vessels in support of loading and unloading cargo for Guam and Micronesia. The Port Authority of Guam is the main lifeline of consumer goods into the island, and as such, recognizes its responsibility to deliver these goods in a timely and efficient manner. In support of this mission the Port Authority also provides land and infrastructure to private interests to further develop the maritime industries on Guam. As a public corporation, the Port Authority dedicates all of its profit to the upgrading of equipment and facilities and the continued growth of the island's seaport.


Historically, Guam has served as a port of call since the 16th century, first catering to the ships of Spain and after the Spanish-American War, to American interests. By the beginning of the 20th century, the United States had established the island as its western Pacific coaling and shipping station. Except for the two year occupation of Guam by the Japanese during World War II, the Naval Administration ran the port until 1951, when command was transferred to the Department of Commerce. After a year of civilian management, the Commercial Port of Guam became a busy center of trade and eventually recognized as one of Guam's most important economic assets.

Built by the U.S. Navy, the commercial port was originally located on 24 acres of land leased from the U.S. Navy. Following its release from the Department of Interior in 1966, 62 acres of land, now known as Cabras Island, was transferred from the Department of Navy to the Government of Guam. Thirty acres went to the commercial port and 32 for the development of an industrial park. To date, over 1,000 acres of land, inclusive of Apra Harbor land, has been transferred from the federal government to the Government of Guam for the use of and control of the Port Authority.

In order to establish an organizational environment more conducive to providing efficient and reliable cargo services, Public Law 13-87 was passed on October 31, 1975, establishing the commercial port of Guam as a public corporation and autonomous instrumentality and naming it the Port Authority of Guam. On June 17, 2002, Public Law 26-106 was passed renaming the Port to Jose D. Leon Guerrero Commercial Port, after the first Commercial Port manager who was very instrumental in having the United Sates transfer the Port facilities and properties to the Government of Guam at no cost in 1968.

Today, the Port of Guam, located along major Pacific shipping and air routes, is an important transportation hub linking the Commonwealth of the Northern Marianas, the Micronesian islands, and the expanding Far East markets with the United States and the rest of the world.
