Sperris Quoit is a ruined megalithic burial chamber or dolmen, and one of a type of tomb unique to West Penwith, located on a moor around 365 metres northeast of Zennor Quoit, being roughly halfway between Zennor and Amalveor, Cornwall.

[3][4] It was in relatively good condition until at least the early 19th century, but there is evidence that stones have been removed since then, for local building work in the village of Zennor.

[5][6] The quoit is situated in rough moorland on the side of Zennor Hill, at about 230 metres above sea level, and is close to several rocky outcrops.

About 12 metres in diameter, five stones were found during the excavations, two standing, and three fallen, of which one has eroded to a stump, although due to heavy vegetation and dense gorse, only one upright of the chamber is visible, which is over 1.5 metres tall.

A cremation pit was discovered during the excavations, and the antechamber faces south.
