Pillar coral (Dendrogyra cylindrus) is a hard coral (order Scleractinia) found in the western Atlantic Ocean and the Caribbean Sea. It is the only species in the monotypic genus Dendrogyra. It is a digitate coral -that is, it resembles fingers (Latin digites) or a cluster of cigars, growing up from the sea floor without any secondary branching. It is large and can grow on both flat and sloping surfaces at depths down to 20 m (65 ft). It is one of the few types of hard coral in which the polyps can commonly be seen feeding during the day.

Color: This coral is usually some shade of beige or brown.

Habitat: Pillar corals are found in the warmer parts of the western Atlantic Ocean and the Caribbean Sea. Within its range, D. cylindrus is common in some places, but rare in other seemingly suitable locations. Some of the islands in the Bahamas have plentiful numbers of colonies as does the north coast of Jamaica.

It used to be common on the reefs off the coast of Florida but has suffered from over-collection there. It seems to be absent from Bermuda and the coasts of Panama and Colombia. It usually grows on level or slightly sloping parts of the reef at depths between 1 and 20 meters (3 ft 3 in and 65 ft 7 in)
