Darenth Wood is a 122.9-hectare (304-acre) biological Site of Special Scientific Interest east of Dartford in Kent.

This ancient semi-natural wood has many rare invertebrates, including thirty-two which are nationally scarce and two which are nationally rare: these are beetles which live in dead and dying oak timber, Grilis pannonicus and Platypus cylindricus.

The wood is crossed by roads and footpaths.
