Absolute Power is a British comedy programme, set in the offices of Prentiss McCabe, a fictional public relations company (or 'government-media relations consultancy') in London, run by Charles Prentiss (Stephen Fry) and Martin McCabe (John Bird).

It started in 2000 on BBC Radio 4, lasting until 2004 with the fourth and final radio series. A six-part television series ran on BBC Two towards the end of 2003; the second six-episode television series ran on BBC Two on Thursdays at 10 pm from 21 July to 25 August 2005. A one-off radio episode was broadcast on 3 November 2006.

The title is taken from a quotation by the historian Lord Acton: "power tends to corrupt, and absolute power corrupts absolutely".
