John Holwell (1648-1686) was a mathematician and astrologer and the author of numerous works on surveying and trigonometry as well as prophecy. A royalist supporter, after the Restoration he was made Royal astronomer and Surveyor of Crown Lands.

His publication of Catastrophe mundi caused much offence, predicting among other things the speedy fall of the Pope, and caused him to be brought before the Privy Council. Exiled to America partly because of his writings, he is recorded as being one of the surveyors of New York where he is reputed to have died of poisoning.
