Caleta de Fuste (also known as El Castillo and Costa Caleta) is the largest community in the municipality of Antigua, Las Palmas, Spain, on the island of Fuerteventura in the Canary Islands.

The area is frequented by a variety of tourists and has numerous hotels, shops, boutiques, bars, cafes and restaurants on or near the beaches. In the main harbour is a castle built as a martello tower by the military engineer Claudio de Lisne in 1743.

In addition to beach activities, local recreation includes sailing, diving, windsurfing and scuba exploration. The ocean waters in the area are known for their dolphin and turtle populations. Nearby is the Championship golf course, one of two at Fuerteventura and the site of the Spanish Open in 2004. The second golf course, finished in 2007, is next to the first.
