Cyclura rileyi, commonly known as the Bahamian rock iguana or the San Salvador rock iguana, is a critically endangered species of lizard native to three island groups in the Bahamas. The species is in decline due to habitat encroachment by human development and predation by feral dogs and cats. There are three subspecies: the Acklins ground iguana (Cyclura rileyi nuchalis), the White Cay iguana (Cyclura rileyi cristata), in addition to the nominotypical subspecies (Cyclura rileyi rileyi ).
