Knockholt is a village and civil parish in the Sevenoaks District of Kent, England. It is located 5 mi (8 km) north west of Sevenoaks & 5.7 mi (9.2 km) south of Orpington, adjacent to the Kent border with Greater London.
 The village is mostly a ribbon development, surrounded by fields that are a part of the Green Belt. There is mixed arable farming. It is in a hilly, rural location, on the top of the dip slope of the North Downs, and has views over London.  The village name, originally Nockholt, is one of many villages in England with a derivation from oak trees, most a strong departure from today's spelling of oak such as Aike.
 The village's name is derived from the Anglo-Saxon āc-holt meaning "oak copse", to which the final -n of the late Old English dative definite article "ðen" ("the") was accreted. The spelling with initial K- is a relatively recent one. Knockholt was included in Orpington Urban District in 1934.  When Greater London was created in 1965, as part of Orpington UD, Knockholt was included in the London Borough of Bromley.  On 1 April 1969, following a concerted campaign by villagers it was removed from the Borough and returned to Kent, being included in Sevenoaks Rural District.
