The Gillhög is a megalithic structure near the village of Barsebäk in the municipality of Kävlinge in Scania, Sweden. It houses Scania’s best-preserved passage grave (Swedish: Gånggrift). The passage grave was constructed between 3500 and 2800 BCE as a megalithic structure of the Funnel beaker culture. It represents a type of construction from the late Neolithic period, consisting of a chamber and a structurally separated lateral passage. This form is primarily found in Denmark, Germany, and Scandinavia, with occasional occurrences in France and the Netherlands. Neolithic monuments serve as expressions of the culture and ideology of Neolithic societies. Their origin and function are considered indicators of social development.

Situated by the Öresund, the hill has always served as a landmark for sailors at the boundary between Lomma Bay and Lundåkra Bay. According to tradition, it was named after the Viking chieftain Erik Gille.
