Richard Hughes Williams (1878 – 26 July 1919), or Dic Tryfan, was a Welsh language writer of short stories, born in Rhosgadfan in the old county of Caernarfonshire (Gwynedd), north Wales. Most of his stories are set in the slate-quarrying communities of his native Caernarfonshire. He was known to the renowned Welsh novelist Kate Roberts, an early admirer of his work who grew up in the same area.
