Robert of Knaresborough was a British hermit and saint who lived in a cave by the river Nidd at Knaresborough, North Yorkshire. Though not formally canonised, he is celebrated as a saint through popular acclaim in both the Anglican and Roman Catholic traditions, his feast day being the 24th of September. Robert was born in York to wealthy parents but shunned that life, living instead as a hermit with a strong following and founding a holy order belonging to the Trinitarians in the market town of Knaresborough. He is also notable in that, after his death, his body exuded a healing oil, making him a myroblyte saint.
