Dichocoenia is a monotypic genus of stony coral in the family Meandrinidae. It is represented by a single species, Dichocoenia stokesii, which is commonly known as pineapple coral, elliptical star coral, or pancake star coral. It is mostly found in the Caribbean Sea and the western Atlantic Ocean.

Dichocoenia is an encrusting coral which forms domes or spheres. Some colonies can create curious shapes, and it just depends on what rock or old coral skeleton Dichocoenia is covering. At the base of the coral, you can see how it appears to be melting on the rock as it slowly encrusts and grows in size.
