Prehistoric religion is the religious practice of prehistoric cultures. Prehistory, the period before written records, makes up the bulk of human experience; over 99% of human experience occurred during the Paleolithic period alone. Prehistoric cultures spanned the globe and existed for over two and a half million years; their religious practices were many and varied, and the study of them is difficult due to the lack of written records describing the details of their faiths.

Göbekli Tepe is a Neolithic archaeological site in the Southeastern Anatolia Region of Turkey. The settlement was inhabited from c. 9500 to at least 8000 BCE, during the Pre-Pottery Neolithic. It is famous for its large circular structures that contain massive stone pillars – the world's oldest known megaliths. Many of these pillars are decorated with anthropomorphic details, clothing, and sculptural reliefs of wild animals, providing archaeologists rare insights into prehistoric religion and the particular iconography of the period. The 15 m (50 ft) high, 8 ha (20-acre) tell is densely covered with ancient domestic structures and other small buildings, quarries, and stone-cut cisterns from the Neolithic, as well as some traces of activity from later periods.
