Big Major Cay (also officially known as Pig Beach), is one of 360 islands found in the Bahamas’ Exuma Cays. It lies inline with hundreds of cays and islands that stretch north from Exuma Island.

The island is world renown for its Pig Beach, getting its name from the Exuma pigs which, along with a few stray cats and goats, are the island’s only inhabitants. There are an estimated 20 to 25 pigs and piglets on the swimming pigs beach.

The island takes its unofficial name from the fact that it is populated by a colony of feral pigs which live on the island. It has become a tourist attraction in modern times. The pigs are known in popular culture as "the swimming pigs" although other islands with swimming pigs exist in the Bahamas.
Some say the pigs are said to have been dropped off on Big Major Cay by a group of sailors who wanted to come back and cook them. The sailors, though, never returned; the pigs survived on excess food dumped from passing ships.

Another legend has it that the pigs were survivors of a shipwreck and managed to swim to shore, while other accounts claim that the pigs had escaped from a nearby islet. Yet others suggest that the pigs were part of a business scheme to attract tourists to the Bahamas while another claims the pigs were stocked on the island in the 1990s by residents of nearby Staniel Cay to raise for food.

Pig beach has become a popular topic on social media sites like Instagram and featured in the television series, The Bachelor. Some people claim to have been bitten by a pig while visiting. They have been written about in a book and claim to be featured in a documentary.
