The Countless Stones, also known as Lower Kit's Coty, is the name of the remains of a Neolithic chambered long barrow near Aylesford in the English county of Kent. The site is one of the Medway megaliths.

Now a jumble of half-buried sarsen stones it is thought to have been a tomb similar to that of the Coldrum Stones. The name is derived from the belief that the chaotic pile of stones from the collapsed tomb were uncountable and various stories are told about the fate of those who tried. Another nearby site that may have been Neolithic is at Cossington.

There are between 19 and 21 stones depending on the authority. They were pushed over in the seventeenth century seemingly before any antiquarian interest was taken in them. William Stukeley attempted to reconstruct the damaged tomb in plan in the eighteenth century.

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. Iron Age activity was found close by.
