Aldbury is a village in Hertfordshire in England, near the borders of Bedfordshire and Buckinghamshire. The nearest town and railway station is Tring. Uphill from the village are the Bridgewater monument and the Ashridge estate.

Its centre has an old church (dedicated to Saint John the Baptist) and primary school, as well as a duckpond and some stocks, making it a popular rural location for films and television: the initial advertisements for the National Lottery was made there despite the fact that villagers were unable to buy tickets at the time.

The largest house in the village is Stocks House which, among its various incarnations, was the rural base of the Playboy Club in the UK.

It should not be confused with the similar sounding Albury, especially Albury, Hertfordshire .
