The Gold Coast was the name for a region on the Gulf of Guinea in West Africa that was rich in gold, petroleum, sweet crude oil and natural gas. This former region is now known as the country Ghana.

The Gulf of Guinea is the northeasternmost part of the tropical Atlantic Ocean from Cape Lopez in Gabon, north and west to Cape Palmas in Liberia. Null Island, defined as the intersection of the Equator and Prime Meridian, is in the gulf.
