Culpepper Island is an uninhabited islet in the Atlantic Ocean located 30 meters off the coast of Barbados.

It was claimed that peasants from Barbados once carried sheep to graze on the island, but this claim seems uncredible because neither the small size nor the very sparse vegetation makes the island attractive for this purpose.

An adult pair of Barbados leaf-toed geckos, once presumed extinct, were discovered on the island in 2011.

On 12 March 2006, members of the region's indigenous Lokono-Arawak and Karifuna-Carib tribes claimed ownership over the island in protest of what they believed to be a violation of international indigenous rights laws by several Caribbean governments.

They claimed to be descendants of Princess Marian, daughter of the last Hereditary Lokono-Arawak Chief Amorotahe Haubariria (Flying Harpy Eagle) of the Eagle Clan Lokono-Arawaks who is buried in the Westbury Cemetery in Barbados.
