John Thomas "Jack" Wooster (30 June 1863 - 20 April 1947) was a politician in the Poplar area. Born in Poplar, Wooster was a life-long member of the Labour movement. In the early twentieth century he joined the Independent Labour Party, the Poplar Trades Council and the Poplar Labour League. In 1918 these were reformed into the Poplar Labour Party and in 1919 was elected a member of Poplar Borough Council, a position he held until his death. During the Poplar Rates Rebellion of 1922 he was not jailed, but was a supporter of the imprisoned councillors. He served as Mayor of Poplar in 1927-28, and represented the borough on the Metropolitan Water Board.
