Hawys Gadarn (Hawys ferch Owain ap Gruffudd ap Gwenwynwyn), also known as the Hardy, the Powerful, the Intrepid, and Hawise de la Pole, (1291 – ) was the daughter of Owen de la Pole and the heir to Powys Wenwynwyn in Wales. She was married to John Charleton after seeking the intervention of Edward II of England to support her inheritance against the schemes of four of her uncles to take her lands.
