Laneast (Cornish: Lanneyst)[1] is a village and civil parish in Cornwall, England, United Kingdom.

The inclusion of St Gulval in the dedication is apparently due to a mistake by Dr. Oliver who understood entries referring to the church of "St Wolvela of Lanestly" as referring to Laneast whereas "Lanestly" is the old name of Gulval.

It was founded and until the Reformation maintained by the Augustinian canons of St Stephen's; thereafter it became a donative served by perpetual curates.

It is unusual in being made of Polyphant stone rather than granite; the two sides of the head are elliptical and have Latin crosses.

[10] Laneast was the birthplace of John Couch Adams, the mathematician and astronomer who discovered Neptune, William Grylls Adams, physicist and professor of Natural Philosophy at King's College, London, and the painter Robert Burnard.
