Douglas Gaston Sydney Camfield (died 27 January 1984) was an accomplished director for television from the 1960s to the 1980s. His programme credits include Z-Cars, Paul Temple, Van der Valk, The Sweeney, Shoestring, The Professionals, The Nightmare Man and the BBC dramatisation of Beau Geste.

Served as a Second Lieutenant in the British Army.

The eight-part Dr Who serial The Invasion, which he directed in 1968, became the most expensive Dr Who serial up to that time.

Became ill during the recording of the Dr Who serial "Inferno", and the remaining studio scenes were directed by the series' producer, Barry Letts, but he was still credited for these scenes.

Suffered from a heart ailment for many years.

Declined the offer to become producer of Doctor Who in 1969, after the departure of Derrick Sherwin.

In an interview on the DVD of the Doctor Who story 'Inferno', Terrance Dicks recalls a conversation in which Camfield lamented the fact that he wanted to make more artistic work like Cocteau or Godard, but that people tended to think of him as Don Siegel. Dicks responded that "There's nothing wrong with being Don Siegel!".
