Old Warden is a village and civil parish in Bedfordshire, England, just west of the town of Biggleswade. It has a population of 275. The village grew up under the protection of the Cistercian Wardon or Warden Abbey nearby.
The village is noted for being the home of the Shuttleworth Trust, an organisation committed to the preservation of transport artefacts — primarily bicycles, motor cars, and aeroplanes — produced in the early part of the 20th century. The corresponding collection is known as the Shuttleworth Collection. The estate also has buildings and gardens, and a small airfield from which many of the historic aircraft fly during the regular flying displays. The estate, museum, and airfield are open to visitors at a price. The estate is also the home of Shuttleworth College founded in 1944.
For local government purposes it forms part of Central Bedfordshire Council and is within the Mid Bedfordshire parliamentary constituency, whose Member of Parliament is currently Nadine Dorries of the Conservative Party.
St Leonard's Parish Church is also located in the village.
