Mary Gunter born Mary Cresswell (1586–1622) was an English Catholic ward and servant who became a celebrated convert to Protestantism. She had become the ward of a man who was executed for his part in a rebellion and was then adopted by his widow. She was subjected to a rigorous conversion after she planned to be a nun. Her husband later published the sermon of her funeral and her biography which went to three editions and it was reprinted as that of an "eminent person" sixty years later.
