Douglas Eden (born 5 March 1939) is an American-born academic and former local politician.
Born in New York, he came to the United Kingdom to undertake his Masters Degree at the University of London in 1960. Following his graduation he served a two year term in the United States Army before returning to the UK.
In 1973 he was elected to the Greater London Council as a Labour Party councillor representing Feltham and Heston. Eden was on the right of the Labour Party and in 1975 became secretary of the Social Democratic Alliance (SDA). Although most of the members of the SDA continued within the Labour Party until 1980/81, Eden was expelled in 1976 and served out his term on the GLC as an Independent until 1977.
He stood for election as as an SDP candidate on two more occasions: European Parliament Elections in 1984 at South Yorkshire and the 1987 General Election at Hornsey and Wood Green.
