Abercych is a village on the west bank of the Afon Cych as it enters the River Teifi. The former is the boundary with the county of Carmarthenshire, and the latter Ceredigion to the north. Abercych is in the southern area of the ancient parish of Manordeifi, which includes Castell Malgwyn.  However, in addresses, the post office uses Llechryd for the south bank of the River Teifi as well.
