Hancock's Half Hour is a BBC television comedy series of the 1950s and 60s written by Ray Galton and Alan Simpson. The series starred Tony Hancock with Sid James. The final series, renamed simply Hancock, starred Hancock alone.

Comedian Tony Hancock starred in the show, playing an exaggerated and much poorer version of his own character and lifestyle, Anthony Aloysius St John Hancock, a down-at-heel comedian living at the dilapidated 23 Railway Cuttings in East Cheam.

The series was influential in the development of the situation comedy, with its move away from radio variety towards a focus on character development.
