Port Royal is a city located at the end of the Palisadoes at the mouth of the Kingston Harbour, in southeastern Jamaica. Founded in 1518, it was the centre of shipping commerce in the Caribbean Sea during the latter half of the 17th century. It was destroyed by an earthquake in 1692 and a subsequent tsunami, and fires. Severe hurricanes have regularly damaged it. Another severe earthquake occurred in 1907.

Port Royal is the former capital city of Jamaica.
