The Isle of Man Constabulary (Manx: Meoiryn-Shee Ellan Vannin) is the national police service of the Isle of Man, an island of 85,000 inhabitants, situated approximately equidistant from Northern Ireland, Wales, Scotland and England.

Nevertheless, the service volunteers itself for inspection by His Majesty's Inspectorate of Constabulary (HMIC) for England and Wales.

Armed officers generally utilize the Glock 17 9x19mm sidearm and favor the Heckler & Koch HK416 5.56x45mm rifle.

[3] In terms of uniform, the force looks very similar to police in the United Kingdom, apart from the Isle of Man custodian helmets worn by male constables and sergeants.

The rank structure of the Isle of Man Constabulary follows the practice of United Kingdom county (as opposed to metropolitan) territorial police forces, except that there are no ranks of chief superintendent or assistant chief constable.
