Aberllefenni is a village in the south of Gwynedd, Wales. It lies in the historic county of Merionethshire/Sir Feirionnydd, in the valley of the Afon Dulas.
It is the location of Foel Grochan, a slate quarry which together with Hen Chwarel and Ceunant Ddu formed the Aberllefenni Slate Quarry, which extracted rock from mediaeval times until the beginning of the 21st Century.
