Winterbourne Chalk Pit is a 0.05-hectare (0.12-acre) geological Site of Special Scientific Interest west of Winterbourne in Berkshire.[1][2] It is a Geological Conservation Review site.[3] It is located within the North Wessex Downs.[4]

The chalk sediments date to the late Cretaceous period, about 80 million years ago.[4] The pit is the only known area containing rocks of this age in the western part of the London Basin.[4] It is rich in macrofossils, particularly belemnites.[5] The site is private land with no public access.
