Poplar was a parliamentary constituency centred on the Poplar district of the East End of London. It returned one Member of Parliament to the House of Commons of the Parliament of the United Kingdom.
The constituency was created for the 1885 general election, and abolished for the 1918 general election, when with very minor boundary changes it was replaced by the new constituency of Poplar South. A small amount of the constituency's territory was added to Bow and Bromley.
It was re-established for the 1950 general election, and abolished again for the February 1974 general election. It was then partly replaced by the new Stepney and Poplar constituency.
1885-1918: In 1885 the area was administered as part of the county of Middlesex. It was located in the Tower division, in the east of the historic county. The neighbourhood of Poplar formed a division of the parliamentary borough of Tower Hamlets. The parliamentary division was part of the East End of London.
