Ricord’s Iguana is known only from the Dominican Republic where it occurs sympatrically throughout most of its range with the Rhinoceros Iguana, Cyclura cornuta. Three disjunct populations of Cyclura ricordii are known:

Barahona Peninsula: a 32 km2 area east of Pedernales surrounds an 8 km2 area of alluvial plain with rich red soil, Los Olivares, which was home to the largest historical population of C. ricordii. As land was cleared and irrigated for agriculture, the iguanas were confined to the surrounding areas of small soil-filled depressions and limestone rock.

Southern Shore of Lago Enriquillo: the status of the population in this area is uncertain; much habitat has been destroyed for agriculture and the remaining natural vegetation is impoverished.

Isla Cabritos: a 4 x 12 km long island in the center of the hypersaline Lago Enriquillo; it is occasionally joined to the mainland via a land bridge depending on precipitation cycles.
