Sidrón Cave (Cueva del Sidrón) is a karst cave site in Asturias, northern Spain, known for its rich Pleistocene fossil deposits and especially for a large assemblage of Neanderthal skeletal remains. Archaeological and palaeontological work at the cave has produced skeletal material and associated fauna used in studies of Neanderthal biology and behaviour.
The excavated deposits contain bones and teeth from multiple individuals along with lithic and faunal remains; researchers have used these materials to investigate diet, population structure and ancient DNA. The site is primarily of scientific and palaeoanthropological interest rather than a developed tourist attraction.
The cave is set within the karst landscape of Asturias and has been subject to controlled excavations and conservation measures led by Spanish research teams.
- Neanderthal remains: Has produced remains of multiple Neanderthal individuals and provided material used in genetic and palaeobiological studies of Neanderthals.
- Karst cave site: Located in the Asturias karst region, the site is a cave system with stratified deposits used by researchers since the late 20th century.
