Slinger's Day is a British sitcom that aired for two series from 1986 to 1987, made by Thames Television for the ITV network.

It was a continuation of Tripper's Day, which had originally come to a natural end after Leonard Rossiter's death, and, despite the overwhelmingly negative response it had drawn from reviewers and a section of the viewing public, was revived this time with Bruce Forsyth as a different character to Rossiter but fulfilling the same role, that of the manager of a London supermarket with largely incompetent staff.

creators Ian Davidson and Peter Vincent, and one episode written by the prolific Andrew Marshall and David Renwick.

Slinger's Day represented Forsyth's only ever situation comedy acting role, and he remained more associated with stand-up routines and game shows.

Cecil Slinger (played by Forsyth) is designated by the Supafare supermarket chain as the new manager in the branch that had previously been run by Norman Tripper.
