Glenn Julian Pennyfather (born 11 February 1963) is an English retired footballer who played as a defender or midfielder. He made 315 appearances in the Football League for Southend United, Crystal Palace. Ipswich Town and Bristol City before moving into non-league football with Stevenage Borough and Canvey Island.
He is a former manager of Chelmsford City, becoming manager after being coach of the club, when he worked alongside long-time friend Jeff King after the pair had joined from a similar arrangement at Canvey Island.
