Bryncroes is a hamlet and former civil parish in Gwynedd in Wales, and lies on the Llŷn Peninsula approximately 2 km west of Sarn Meyllteyrn. The parish was abolished in 1934 and divided between Botwnnog and Aberdaron. The village was the scene of fierce protests between 1969 and 1972 when it was proposed to close the village school. However, the protests were in vain and the school closed, and is now a village community centre.
