The Cayman Islands ( /ˈkeɪmən/ or /keɪˈmæn/) is a British Overseas Territory located in the western Caribbean Sea. The territory comprises the three islands of Grand Cayman, Cayman Brac, and Little Cayman, located south of Cuba and northwest of Jamaica. The Cayman Islands are considered to be part of the geographic Western Caribbean Zone as well as the Greater Antilles. The territory is a major world offshore financial centre.

The Cayman Islands were first logged as sighted by Christopher Columbus on 10 May 1503 during his fourth and final voyage to the New World. He named the islands Las Tortugas after the large number of sea turtles observed there. The first recorded English visitor to the islands was Sir Francis Drake in 1586. He subsequently named the islands "Cayman" after caiman, a Neo-Taino word for "alligator".

The Cayman Islands remained largely uninhabited until the 17th century. While there is no archaeological evidence for an indigenous people on the islands, a variety of settlers from various backgrounds made their home on the islands, including pirates, refugees from the Spanish Inquisition, shipwrecked sailors, and deserters from Oliver Cromwell's army in Jamaica.
