Greatstone is a village on the coast of Romney Marsh in Kent, England.

There was widespread development in the 1960s and 1970s, however, leading to a sizable community.

The beach features on Teletubbies on BBC, Series 1: 11.

From 1937 until 1967 the town also had a national railway station at Greatstone-on-Sea Halt.

Stagecoach in East Kent runs local buses to other towns.
