The Flag of Palau was adopted on 1 January 1981, when the island group separated from the United Nations Trust Territory. As with the flags of several other Pacific island groups, light blue is the color used to represent the ocean and the nation's place within it. While this puts Palau in common with the Federated States of Micronesia and other neighboring island groups, the disc on the flag is off-centre like that of the flag of Bangladesh, but in this case the disc represents the moon instead of the sun. The current flag was introduced in 1981 when Palau became a republic.

Palau has flags for its sixteen states.
