Deepdene was an estate and country house, located in Dorking, Surrey, England.
The estate was built by Thomas Hope, and his architect William Atkinson (architect) and occupied by his son, the MP Henry Thomas Hope.
The gardens were laid out in a contemporary Italianate picturesque style. The horticulturalist and planner John Claudius Loudon praised the gardens as an exemplar of landscape architecture, one of the earliest uses of that phrase.
The house and gardens were demolished in 1967.
