Seven of One, stylised as 7 of 1, is a British sitcom anthology series that aired on BBC2 in 1973. Starring Ronnie Barker, Seven of One is a series of seven separate 30-minute episodes that would serve as possible pilots for sitcoms. Originally it was to be called Six of One, which Barker planned to follow up with another series called And Half a Dozen of the Other. This was a BBC equivalent of a similar showcase for London Weekend Television called Six Dates with Barker created in 1971.

In addition to Barker, Seven of One also featured Roy Castle, Bill Maynard, Talfryn Thomas, Prunella Scales, Glynn Edwards, Joan Sims, Keith Chegwin, Leslie Dwyer, Robin Parkinson, Sam Kelly, Christopher Biggins, Richard O'Callaghan, Yootha Joyce, David Jason, and Avis Bunnage in supporting roles. The series was released on BBC DVD in 2005.
