Little Kit's Coty House, also known as Lower Kit's Coty House and the Countless Stones, is a chambered long barrow located near to the village of Aylesford in the southeastern English county of Kent. Constructed circa 4000 BCE, during the Early Neolithic period of British prehistory, today it survives in a ruined state. Archaeological evaluation trenching in 1989 found no clear evidence of any surrounding quarry ditch which would normally have been excavated to provide material for a covering barrow.
