Canonbury is a residential district in the London Borough of Islington in the north of London. It is roughly in the area between Essex Road, Upper Street and Cross Street and either side of St Paul's Road. In 1253 land in the area was granted to the Canons of St Bartholomew’s Priory, Smithfield and became known as Canonbury. The area continued predominantly as open land until it was developed as a suburb in the early 19th century. In common with similar inner London areas, it suffered decline when the construction of railways in the 1860s enabled commuting into the city from further afield. The gentrification of the area from the 1950s included new developments to replace war-damaged properties in Canonbury Park North and South as well as restoration of older buildings.

East Canonbury is the south-eastern corner of the district, bordering on the Regents Canal. Parts of this area were transferred to the district from the London Borough of Hackney in a boundary adjustment (along the line of the northern tow-path of the canal), in 1993.
