Pantdreiniog-stenen var en skiferbrud i byen Bethesda i Nordv Wales. Den blev udnyttet mellem omkring 1825 og 1923. Den spillede en vigtig rolle i Penrhyn Great Strike, Storbritanniens længste industrielle konflikt.
Den tidlige historie om bruddet er uklar, men det ser ud til at være startet omkring 1825, og var bestemt i drift i 1845, da skiffermanden John Hughes fra Maentwrog faldt i sin død i pitten, som da var 40 meter dyb. I 1860, ejet af William Owen, producerede Pantdreiniog Slate Company 3.000 tons skifer, hvilket faldt til 1.372 tons produceret af 30 mænd i 1864. I løbet af 1860'erne udvidede bruddet og overtog det nærliggende Coetmor Quarry. Engang i slutningen af 1860'erne lukkede bruddet.
