Port Antonio (Jamaican Patois: Puot Antuoni) is the capital of the parish of Portland on the northeastern coast of Jamaica, about 100 km (60 miles) from Kingston.

It is the island's third largest port, famous as a shipping point for bananas and coconuts, as well as one of its most important tourist attractions, tourism being a major contributor to the town's economy.

[2] In the 1880s, Lorenzo Dow Baker started the banana trade in Jamaica and successfully promoted Port Antonio as a destination for wealthy American travelers.

He subsequently bought nearby Navy Island, part of historic Fort George in Port Antonio as well as hundreds of acres of farmland along the Portland coast.

Port Antonio was the terminus of the now abandoned railway from Kingston via Spanish Town and Bog Walk, which was primarily built to serve the banana export trade.

Local sites such as the town's courthouse, the tax office (which in the film served as the police station), Blue Lagoon, Frenchman's Cove, Winifred Beach, were used as the backdrop to the story.

The 1988 romantic comedy drama film Cocktail starring Tom Cruise was partially shot in Port Antonio, also with scenes of Frenchman's Cove and Blue Lagoon.
