Nashenden Down is a 55-hectare (140-acre) nature reserve on the southern outskirts of Rochester in Kent.

It is managed by the Kent Wildlife Trust, and is in the Kent Downs Area of Outstanding Natural Beauty.

[1] This nature reserve was created from a large arable field in 2009, and it is being regenerated with chalk grassland species, partly by colonisation from a steep bank which escaped ploughing and partly by seed spreading.

An area of scrub provides a habitat for birds.

[1] There is access to the site from Nashenden Farm Lane.
