Betts Park is a public park in Anerley, London Borough of Bromley, in southeast London, England. It is approximately 13 acres and has a number of attractions, including part of the old Croydon Canal and the Heart of Anerley obelisk. The current park was opened in December 1928 and extended throughout the 1930s, with the final addition of "new fields" by the King George V Memorial Trust in 1937. The boundaries of the park mirror the outline of an ancient copse dating back over 1000 years.
