Knatts Valley is situated in the West Kingsdown civil parish in Kent in England.
It was originally a rural community consisting mainly of several small holdings: the principal farms being Knatts Farm (sheep), giving its name to the area; and Maplescombe Farm (cattle). One settlement in the valley is Romney Street; the word street meaning hamlet in these parts of Kent. To the east there is a development of housing within a wooded area, mainly of detached housing, and to the west is a similar development — "East Hill, Kent". There is a golf course here, a residential caravan park and a public house offering meals called "The Fox and Hounds" at Romney Street. Here is also an unlicensed airstrip, being part of Romney Street Farm, with a north-south grass runway east of Upper Wood.
