Monmouth School for Boys is a public school (independent day and boarding school) for boys in Monmouth, Wales. The school was founded in 1614 with a bequest from William Jones, a successful merchant and trader. The School is run as a trust, the William Jones's Schools Foundation, by the Worshipful Company of Haberdashers, one of the livery companies, and has close links to its sister school, Haberdashers' Monmouth School for Girls. In 2018, the Haberdashers renamed their group of schools in the town, the Monmouth Schools, and made corresponding changes to the names of the boys' and girls' schools.
