Boscawen-Ûn (grid reference SW412273) is a Bronze Age stone circle close to St Buryan in Cornwall, UK. It consists of nineteen upright stones in an ellipse with another, leaning, middle stone just south of the centre. There is a west-facing gap in the circle, which may have formed an entrance. The elliptical circle has diameters 24.9 and 21.9 metres (82 and 72 ft). It is located at grid reference SW412274.
The Gorseth Kernow was inaugurated here in 1928. An old Welsh triad mentions one of the three principal gorseddau of the Island of Britain as "Beisgawen yn Nyfnwal" (Boscawen in Dumnonia), which was taken to refer to Boscawen-Ûn by the Gorseth's founders. That Welsh triad dates to only the 18th century when it was made up by Iolo Morganwg, Edward Williams.
