Gwent Police (Welsh: Heddlu Gwent) is the Home Office police force responsible for policing the local authority areas of Blaenau Gwent, Caerphilly, Monmouthshire, Newport and Torfaen in southeast Wales.
It was formed in 1967 as an amalgamation of the Monmouthshire Constabulary and Newport Borough Police. In 1974 its area was realigned to cover the new administrative county of Gwent. In 1996, the force's area was expanded to cover the former Rhymney Valley district area as a consequence of it becoming part of the Caerphilly county borough, in order to incorporate the entirety of the county borough in the police area.
The Force has its headquarters at Croesyceiliog in Cwmbran. The Chief Constable is Mike Tonge. Gwent Police has a tradition of high scores in government league tables, particularly with regard to crime clear-up rates .
