Saint Elizabeth, one of Jamaica's largest parishes, is located in the southwest of the island, in the county of Cornwall. Its capital, Black River, is located at the mouth of the Black River, the widest on the island.

Black River is the capital of St. Elizabeth Parish, in southwestern Jamaica. It developed as a port around the mouth of the river of the same name. Today, the city is a centre of environmental tourism and a gateway to the Treasure Beach resort area. Treasure Beach and Crane Beach are to the south-east, with Luana Beach to the west. In the 18th and early 19th centuries, it was a thriving sugar port with a market for African slaves.
