Nash Point (Welsh: Trwyn yr As) is a headland and beach in the Monknash Coast of the Vale of Glamorgan in south Wales, about a mile from Marcross.

The lighthouse meadow is a Site of Special Scientific Interest, containing rare plants such as the tuberous thistle, and other wildlife such as choughs can be seen.

Parts of the section of the Glamorgan Heritage Coast where the lighthouse stands consists of "cliffs of Lias limestone interbedded with softer erodible material" and has been identified as potentially at risk from erosion and flooding.

[6] A study of the rocks shows that they exemplify "a 12,000 year old sequence of tufa, scree and slope deposits containing abundant fossil snails", while the Nash Bank offshore is formed by "Jurassic mudstones overlain by bands of sand and gravel".

Its construction is said to have been spurred by the wreck of The Frolic on the Nash Sands in March 1831,[8] which resulted in over 50 deaths, including that of Lt-Col N McLeod.
