Red Cap is a British television drama series, produced by Stormy Pictures for the BBC and broadcast on BBC One. A total of thirteen episodes were broadcast over the course of two series, beginning with a feature-length pilot on 28 December 2001. The series follows the investigations and personal relationships of a British Army Special Investigation Branch unit of the Royal Military Police based in Germany.

The Royal Military Police (RMP) is the corps of the British Army responsible for the policing of army service personnel, and for providing a military police presence both in the UK and while service personnel are deployed overseas on operations and exercises. Members of the RMP are often known as 'Redcaps' because of the scarlet covers on their peaked caps and scarlet coloured berets.
