William was a BBC television series based on the Just William series of books written by Richmal Crompton. It ran for two series from 1962 to 1963. 12 episodes were made in all, each of half an hour long. It was filmed in black and white.

All episodes were believed to have been wiped by the BBC, but in 2016 the British Film Institute announced it had recovered the second episode of the first series, William and the Leopard Hunter. All eleven other episodes of the comedy were listed as missing.
