The Army Cadet Force (ACF) is a cadet organisation based in the United Kingdom. It is a voluntary youth group sponsored by the Ministry of Defence (British Army). Local units of the ACF, called Detachments, are based in towns and villages across the UK and formed of those cadets and Cadet Force Adult Volunteers (CFAVs) parading together at that location.

Detachments are grouped into Areas, which may also be termed Company, Squadron, Battery or Group; which are grouped into Counties, also known as Sectors or Battalions. ACF Counties may encompass one or more geographical counties. Counties are commanded by British Army Regional Points of Command (RPOCs), which report to Regional Command. Each RPOC has a Cadets Branch, responsible for policy and administrative support, and Cadet Training Team, formed of Full-time Reservists and CFAVs who provide support and senior cadet training.

Detachments may be numbered, named for the locality in which it resides, named in accordance with specific regimental or historical links, or a combination of those. Each detachment, and in some cases entire Areas and Counties, will be affiliated with a Regiment or Corps of the British Army, and wear their insignia including cap badge, beret and stable belt.

The following list is broken down into RPOCs, Counties, Areas and Detachment localities.
