Hester (or Esther) Biddle (c. 1629–1697) was an English Quaker writer and itinerant preacher who "addressed pugnacious pamphlets to those who persecuted religious dissenters, worshipped in the Anglican church, or refused to help the poor." She became a Quaker in 1654. Her subsequent preaching took her to Ireland and Scotland, Newfoundland, the Netherlands, Barbados, Alexandria and France.
