Adrian Biddle, B.S.C. (20 July 1952, Woolwich, London – 7 December 2005, London), was an English cinematographer.

Biddle was a talented swimmer in his youth, and it was through this that he broke into the film industry. In 1967 the underwater photographer Egil Woxholt hired him to be his apprentice. Uncredited, he worked in this capacity on both the James Bond film On Her Majesty's Secret Service (1969) and Murphy's War (1971).

After this, Biddle worked for Ridley Scott's advertising company R.S.A. where worked on a large number of advertisements with Scott and when Scott moved into films, Biddle followed him.

On The Duellists (1977) he was working as a clapper loader, before advancing to the position of focus puller on Alien (1979).

Following Alien, Biddle returned to working as a cinematographer on advertisements. During this time he developed a number of new lighting techniques and worked on a number of famous campaigns. His most famous advertisement was 1984 (1984), directed by Ridley Scott, for Apple. The advert's photography, combined with a personal recommendation from Scott, prompted James Cameron to hire Biddle as his cinematographer for the film Aliens (1986), the first film Biddle worked on in this role.
