Queendown Warren is a 22.2-hectare (55-acre) biological Site of Special Scientific Interest south-east of Rainham in Kent.

A major extension to the reserve was made in 1999 with the addition of pasture on the opposite side of the valley facing the Main Bank.

At the bottom of the bank, there is a colony of rabbits which, together with grazing cattle, help to maintain the short sward, essential for the maintenance of many orchid populations.

Potters Wood contains native broad leaved trees - oak, ash, beech, birch and wild cherry - and some sweet chestnut coppice managed by traditional methods.

The southern part of the wood is on the chalk and has the remnants of many large beech trees which fell during the storm of October 1987.
