Guam Flag

The deep blue field represents the Pacific Ocean surrounding Guam. The central seal depicts a coconut palm in front of the shore of Hagåtña Bay with a coconut tree, canoe sails, and a desert rose flower—Guam’s national flower—signifying self-sustenance, resilience, and serenity. The red border around the oval echoes pride and vitality. Together, the elements reflect Guamanian identity and connection to land and sea.

The coat of arms originated during U.S. Navy administration in 1946 and was placed within the iconic oval in 1948. The flag was standardized that year to give Guam a unique emblem reflecting indigenous Chamorro culture. During WWII, when U.S. forces reoccupied the island from Japanese control, the olive green variant was also used. The flag was reaffirmed as territorial emblem and has flown ever since in residences, schools, and government buildings.

On a dark blue background lies a horizontal red-bordered oval slightly off-center toward the hoist. Within the oval, the seal of Guam features a coconut tree by the shoreline, canoe, bay, and the word ‘GUAM’ in bold red letters. The unique 22:41 proportion creates a slender flag shape uncommon among U.S. territories.

The flag of Guam is flown on public buildings, schools, and official ceremonies alongside the U.S. flag. Local law mandates the flag be raised at sunrise and lowered at sunset; it must never touch the ground. Half-masting occurs during national mourning or significant local commemorations. The flag is also used by Guam’s national sports teams and cultural delegations, reinforcing pride and identity.
