The 21-year-old, who has been with the Terriers since 2009, had loan spells with Brentford and Crawley Town last season.
Huddersfield boss Mark Robins told the club's official website: "Scunthorpe are a team who expect to be pushing for promotion so it should be a challenge for Jimmy."
Spencer has made three appearances for Huddersfield.
