The Goat's Hair Twin Caves are in the British Overseas Territory of Gibraltar.

The caves are listed in the Heritage and Antiquities Act as they are sites of Palaeolithic and Neolithic archaeology.

Both caves have large, triangular-shaped entrances, and were formed along vertical fractures.

This name was given to them as it was a goatherd refuge in the 19th century and this meant a large amount of goat's hair found attached to the cave walls.

During these excavations, there was the discovery of a "prehistoric ceremonial burial" on the northern wall of one of the two caves revealing a female human skeleton with a crushed skull[2] surrounded by various pottery vessels, bone pendants, flint blades, armlets and anklets.
