Personal Aide-de-Camp to the King is an appointment in the Royal Household of the United Kingdom. It is distinct from that of other aides-de-camp, in that it is only bestowed on members of the British royal family holding military rank. The appointment may be signified by the post-nominal letters 'ADC(P)'. It is an honorary role with few duties or responsibilities attached; in the 20th century the Personal Aides-de-Camp were specifically listed as riding close behind the Gold State Coach at each Coronation, and walking or riding close behind the Gun Carriage at each State Funeral, of a monarch.

An aide-de-camp is a personal assistant or secretary to a person of high rank, usually a senior military, police or government officer, or to a member of a royal family or a head of state.
