Andros Conservancy and Trust (ANCAT) is a Bahamian, non-profit, conservation NGO, informally started in 1997 and officially founded in 1999, which is working toward protecting the marine environment and natural resources of Andros Island in the Bahamas. Its purpose is to protect, preserve, enhance and restore the ecological environment on Andros Island through education, conservation, and management.

Andros Island is of great importance to the preservation of natural resources in the Bahamas because it is a naturally functioning giant ecosystem. At 2300 square miles in size, it is perhaps the largest tract of unexplored land in the Western Hemisphere and provides a habitat for endangered birds, iguanas and crabs, as well as more than 40 known species of wild orchids.

A large part of the ecosystem encompasses one of longest and best-preserved barrier reefs in the world. Andros Island also has the highest known density of blue holes in world and holds the largest reservoir of fresh water in the Bahamas.

Because of its stellar work on Andros Island, ANCAT has captivated the attention of the conservation community nationally, regionally, and internationally. Together with local stakeholders, the Bahamas National Trust, the Bahamas Reef and Environment Education Foundation, and The Nature Conservancy, they succeeded in getting the Bahamian Government to establish the Central Andros National Park in April 2002.
