Circles of Deceit is a British television thriller series, produced by Yorkshire Television, first broadcast on ITV on 16 October 1993.

The series stars Dennis Waterman as John Neil, a former SAS officer, and Falklands veteran, later recruited as an agent and investigator for the Security Service (MI5). Some years previously Neil's wife and child were killed by an IRA bomb. In his despair, Neil turned to drink and quit the service. He took refuge from the world in a remote house deep in the Yorkshire countryside, until MI5 come calling with a job offer he can't refuse, however reluctantly.

A VHS video of the self-titled pilot was released in the US in 1994. The complete series was later released on Region 1 DVD in the US by Acorn Media on 17 May 2011. On 23 April 2018, nearly twenty-five years after the broadcast of the self-titled pilot, the complete series was released on Region 2 DVD in the UK by Strawberry Media.
