Hampden, a small town in North Otago, New Zealand, lies close to the North Otago coast, 35 kilometres south of Oamaru and 80 kilometres north of the city of Dunedin, to both of which it is connected by State Highway 1.

The Moeraki Boulders are unusually large spherical boulders lying along a stretch of Koekohe Beach on the wave-cut Otago coast of New Zealand between Moeraki and Hampden. They occur scattered either as isolated or clusters of boulders within a stretch of beach where they have been protected in a scientific reserve. These boulders are grey-colored septarian concretions, which have been exhumed from the mudstone and bedrock enclosing them and concentrated on the beach by coastal erosion. Especially in recent years, the boulders have been a popular tourist attraction.
