Erisey was a manor on the Lizard Peninsula, Cornwall, UK and is the surname of the family that built the house.

The Grade II listed building was built by Richard Erisey in the 17th-century and in the 18th-century was owned by the Boscawan family of Tregothnan.

James Erisey (died 1522) was the Sheriff of Cornwall in 1513 and there is a brass memorial recording his death and that of his wife, Margaret in the parish church.

Admiral Boscawen (1711–1761) of Tregothnan purchased the property from the co-heiresses of the Erisey family sometime in the middle of the 18th-century.

[4][5] Oliver Rackham, who studied the history and development of the countryside considered the pattern of farms and fields on the Lizard to be largely complete by the 14th-century.
