Jackson's Bay Cave is a very large cave on the Portland Ridge in Clarendon near the south coast of Jamaica.

[2] The longest of them, Jackson Bay Great Cave is over 3.360 kilometres (2.088 mi) long.

Pottery shards, rock carvings and rock paintings suggest that the caves were used by the Arawak Indians or Taínos.

A specimen of the extinct Jamaican monkey (Xenothrix mcgregori) was found by an American Museum of Natural History expedition c. 1993–1996.

Fossil remains of the Jamaican flightless ibis (Xenicibis xympithecus) and the Jamaican caracara (Caracara tellustris) have also been found there.
