Conception Island National Park, Protected maritime national park in central Bahamas archipelago.

Conception Island National Park is a protected maritime reserve in the central Bahamas archipelago. It features mangrove forests, coral reefs, and coastal vegetation across an uninhabited island.

Washington Irving named Conception Island as one of Christopher Columbus's landfalls on his 1492 voyage, but other historians rejected the claim and proposed different islands. The Bahamas National Trust now administers the 810-hectare park covering Conception Bank, Conception Island, Booby Cay and the South Rocks.

The park is administered by the Bahamas National Trust, which covers Conception Bank: Conception Island, Booby Cay, the South Rocks and scattered islets. Law prohibits exploiting the green turtle population, though enforcement is difficult and visitors occasionally remove turtles. The endemic Conception Bank silver boa, named for the silver palm where it was first found, lives only here.

The park lies between Cat Island to the north and Rum Cay to the south, and is reached only by boat; there are no facilities or moorings on the island. Conception Creek, the salty bay on Conception Island, is a hotspot of green turtle activity, so boaters should avoid anchoring over seagrass there. The park is administered by the Bahamas National Trust.

In 2015 a boa new to science was found on Conception Bank, reportedly first in a silver palm, and named Chilabothrus argentum. It is endemic to the park. Conception Creek, a salty bay, is a hotspot of green turtle activity.
