Gunnersbury Park is a park between Acton, Brentford, Chiswick and Ealing, West London, England. Purchased for the nation from the Rothschild family, it was opened to the public by Neville Chamberlain, then Minister of Health, on 21 May 1926. The park is currently jointly managed by Hounslow and Ealing borough councils. A major restoration project funded by the Heritage Lottery Fund was completed in 2018. The park and garden is Grade II listed.
