Richard Bonython (1580–1650) was an English magistrate and early settler and landowner in New England. The second son of a Cornish landowner, he served as a military officer before emigrating to the Province of Maine in 1630 with his family. He co-owned a portion of land adjacent to the Saco River and was appointed a magistrate. During his judicial career his son John was brought before the court and was eventually outlawed, for which he was mentioned in an 1830 poem of John Greenleaf Whittier. Bonython later served as a councillor to the deputy governor of Maine Thomas Gorges.
