The King's Regulations is a collection of orders and regulations in force in the Royal Navy, British Army, Royal Air Force, and Commonwealth Realm Forces, forming guidance for officers of these armed services in all matters of discipline and personal conduct. Originally, a single set of regulations were published in one volume. By the mid 19th century, there were separate editions of the Queen's Regulations for the Navy and the Army, and there is now one for each of the United Kingdom's armed forces.
