Enfield Grammar School (abbreviated to EGS; also known as Enfield Grammar) is a boys' comprehensive school and sixth form with academy status in Enfield Town in the London Borough of Enfield in North London. The school was founded in 1558 and inherited part of a charitable endowment that had endowed the earlier Enfield chantry-school. In 1967, the school was amalgamated with Chace Boys School to form a comprehensive school. The two schools were separated again in 1970. In 2023, the school started to accept female applications, for 6th form, for the first time in the school’s 500 year history.
