Fron-Boeth and Pant Mawr quarries were two closely related and interconnected quarries on the western slopes of Moelwyn Mawr in Gwynedd, North Wales. Pant Mawr operated from around 1850 to 1879, and was partly re-opened in 1886 when it was amalgamated with Fron-Boeth. Both quarries closed during the First World War. Finished product was transported to the slate quays of Porthmadog by the Croesor Tramway.
