Northiam is a Site of Special Scientific Interest in the county of East Sussex, England. It is a disused quarry, partially flooded, revealing structures of geological interest.

The disused (and partially flooded) quarry at Northiam displays an excellent section through the Northiam Sandstone Member of the Wadhurst Clay Formation, for which this is the type locality. The rocks comprise complex channel-fill sandstones (including sedimentary bar-forms and current direction indicators).
The site is important for the study of the Wadhurst Clay Formation palaeoenvironments and palaeogeography. It is particularly important for comparison with other sandstone members of the Hastings Beds Group clay formations.
