Tring trɪŋ is a market town and civil parish in the Borough of Dacorum, Hertfordshire, England. It is situated in a gap passing through the Chiltern Hills, classed as an Area of Outstanding Natural Beauty, from Central London. Tring is linked to London by the Roman road of Akeman Street, by the modern A41 road, by the Grand Union Canal and by the West Coast Main Line to London Euston. Settlements in Tring date back to prehistoric times and it was mentioned in the Domesday Book; the town received its market charter in 1315. Tring is now largely a commuter town within the London commuter belt.
As of 2013, Tring had a population of 11,731.
The name Tring is believed to derive from the Old English Tredunga or Trehangr, 'Tre' meaning 'tree' and the suffix 'ing' implying 'a slope where trees grow'.
There is evidence of prehistoric settlement with Iron Age barrows and defensive embankments adjacent to The Ridgeway, and also later Saxon burials. The town straddles the Roman road called Akeman Street, running through as the High Street.
Tring was the dominant settlement in the area, being the primary settlement in the Hundred of Tring at the time of the Domesday Book (1086). Tring had a large population and paid a large amount of tax relative to most settlements listed in that survey. Landholdings included the manor of Treunga, assigned to Count Eustace II of Boulogne by William the Conqueror.
In 1315 the town was granted a market charter by Edward II. This charter gave Faversham Abbey the right to hold weekly markets on Tuesdays, and a ten-day fair starting on 29 June, the Feast of Saints Peter and Paul. It also prevented the creation of any rival markets within a day's travel of the town. The tower of the Church of St Peter and St Paul was built between 1360 and 1400.
Until 1440, there was a small village east of Tring called Pendley (or Penley, Pendele, or Pentlai). The landowner Sir Robert Whittingham received a grant of free warren from King Henry VI.
