King Street Junior and its sequel King Street Junior Revisited are a series of long running comedies written by former teacher Jim Eldridge.

The series is about the bickering staff of King Street Junior School, a small school in a multiracial area. In the original series, the head of the school is permanently harassed headmaster Mr. Beeston (James Grout). In the first two series there was new ingenuous Mr. Brown (Peter Davison), an idealistic teacher who had just left work in the oil industry. He later left to get a better teaching job and was replaced by solicitor-turned-teacher Mr. Sims (Karl Howman).

Other staff include world-weary transport-mad Deputy Head Mr. Holliday (Tom Watson), calm secretary Mrs. Stone (Margaret John), mother-domineered spinster Miss Lewis (Marlene Sidaway), the young left-wing radical Mr. Long (Paul Copley), totally terrifying music teacher Mrs. Rudd (Vivienne Martin), and the attractive no-nonsense Mrs. Patterson (Deirdre Costello).

After 10 series most of the original staff had left with Miss Lewis now Deputy Head and Mr. Long now slightly more disillusioned. A sequel, King Street Junior Revisited was created, with new staff to reflect the changes in education since the series ended. Among the new teachers were Miss Reid (Jacqueline Beatty) who had joined the school in the old series, new head teacher Mrs. Devon (Carolyn Pickles), vegetarian pacifist Miss Featherstone (Teresa Gallagher), free-enterprise proponent Mr. Maxwell (Michael Cochrane), and Asian secretary Mrs. Khan (Janice Acquah). In the final series another head teacher took over King Street - Mrs. Eastwood (Brigit Forsyth), who had the habit of rubbing everyone up the wrong way.
