The Isle of Dogs is a large peninsula bounded on three sides by a large meander in the River Thames in East London, England, which includes the Cubitt Town, Millwall and Canary Wharf districts. The area was historically part of the Manor, Hamlet, Parish and, for a time, the wider borough of Poplar. The name had no official status until the 1987 creation of the Isle of Dogs Neighbourhood by Tower Hamlets London Borough Council. It has been known locally as simply "the Island" since the 19th century.
The whole area was once known as Stepney Marsh; Anton van den Wyngaerde's "Panorama of London" dated 1543 depicts and refers to the Isle of Dogs. Records show that ships preparing to carry the English royal household to Calais in 1520 docked at the southern bank of the island. The name Isle of Dogges occurs in the Thamesis Descriptio of 1588, applied to a small island in the south-western part of the peninsula. The name is next applied to the Isle of Dogs Farm shown on a map of 1683. At the same time, the area was variously known as Isle of Dogs or the Blackwell levels. By 1855, it was incorporated within the parish of Poplar under the aegis of the Poplar Board of Works.
