The Deputy Chief of the Naval Staff (DCNS) is a senior appointment in the Royal Navy, responsible for a significant portion of the navy's operations and development. The role sits within the Naval Staff, the central staff of the Royal Navy, based at the Ministry of Defence in London.

The DCNS assists the First Sea Lord and Chief of the Naval Staff in the discharge of their duties and deputizes for them when required. The specific portfolio of responsibilities held by the DCNS can vary depending on the prevailing needs of the Royal Navy and the individual appointed. Generally, the DCNS is responsible for aspects of naval capability, including requirements generation, procurement, and in-service support. This often involves overseeing various directorates and branches within the Naval Staff.

The DCNS is typically a Rear Admiral or Vice Admiral. The appointment is considered a stepping stone to more senior positions within the Royal Navy, such as First Sea Lord. The current responsibilities of the DCNS are focused on ensuring the Royal Navy remains a modern, capable, and effective fighting force. The role requires close collaboration with other branches of the armed forces, government departments, and international allies.
