The Kent Downs is an Area of Outstanding Natural Beauty (AONB) in Kent, England. They are the eastern half of the North Downs and stretch from the London/Surrey borders to the White Cliffs of Dover, including a small section of the London Borough of Bromley. The AONB also includes the Greensand Ridge, a prominent sandstone escarpment which lies south of the chalk escarpment of the North Downs.

An Area of Outstanding Natural Beauty is one of 46 areas of countryside in England, Wales, or Northern Ireland that has been designated for conservation due to its significant landscape value. On 22 November 2023 the AONBs in England and Wales adopted a new name, National Landscapes, and are in the process of rebranding.
