'''Dduallt''' ({{langx|en|Black hill}}; {{IPA|cy|ðɨ.æɬt}}) is a mountain in central Snowdonia, north Wales. It is the sister peak of Rhobell Fawr.
It lies north of the A494 between Dolgellau and Llanuwchllyn. Its eastern slopes are the source of the Afon Dyfrdwy (River Dee).<ref>Nuttall, John & Anne (1999). The Mountains of England & Wales - Volume 1: Wales (2nd edition ed.). Milnthorpe, Cumbria: Cicerone. {{ISBN|1-85284-304-7}}.</ref>
It is normally climbed from the SW (often with Rhobell Fawr) as there are large boggy areas to the N and E and very steep E face.
