Rhosgadfan is a Welsh village in the county of Gwynedd, formerly in the historic county of Caernarfonshire, and in the community of Llanwnda. It is notable as the birthplace of Kate Roberts, one of the greatest Welsh-language writers of the 20th century; her childhood home is now a museum (see below).
