Gadebridge House was a country house at Gadebridge in Hertfordshire.

The house was built for Sir Astley Paston Cooper, a surgeon, who moved there in 1811.^[1] In around 1840 Cooper commissioned an iron bridge as part of the approach to the site.^[2] The house was inherited by Lionel Hervey-Bathurst in 1905, following the death of the 3rd Baronet.^[3] The house passed down the Paston-Cooper family until it became Gadebridge Park School in 1914.^[1] Although the site accommodated a temporary army camp during World War I, the house remained a school until 1963 when the school was forced out of its premises by the Commission for New Towns as part of its development of the new town.^[4] The house was demolished and Kodak built a Marketing Education Centre on the site: the centre was itself demolished in 1995 and the site is now used for housing.^[1]
