Ephraim Pagit (Pagitt) (c. 1575 – April 1647) was an English clergyman and heresiographer. His Heresiography of 1645 was a precursor of the better-known Gangraena, and is a well-referenced account of contemporary sectarian Protestantism in England. In fact the Oxford English Dictionary indicates that the title of this book was a neologism, derived by analogy from Christianography, an earlier title, to indicate a catalogue or classification of heretics. By political conviction Pagit was a royalist, but he was sufficiently opposed to the religious Independents to support Presbyterianism.
