John Nicoll Powrie (9 May 1898-1977) was a Labour Party politician active in south east London.
An engineer's millwright, he was born in Dundee, Scotland. He served in the Royal Engineers during the First World War before he moved to the Kent suburbs of London, becoming a shop steward at Woolwich Arsenal for 12 years, and later chairman of Dartford Divisional Labour Party. He unsuccessfully contested the parliamentary seat of Sevenoaks for the Labour Party at the the 1951 and 1955 general elections.
He became a member of Erith Borough Council in 1938, and was Mayor of Erith in 1949-50, and a member of Kent County Council from 1949-65.
With the creation of the Greater London Council, Powrie was elected one of four councillors representing the new London Borough of Bexley, which included the area of the former Borough of Erith. He was defeated at the second Greater London Council elections in 1967, when labour lost all three Bexley seats to the Conservative Party.
