This is a list of the areas of London, in alphabetical order. In political or administrative usage (and other than the City and the London boroughs themselves) contemporary areas of London are informal, often being based on or adapted from historic parish or borough boundaries abolished by 1965. In ecclesiastical usage, many of the districts exist as parishes either for the established Church of England or other religious bodies. For electoral purposes all boroughs are divided into wards which may share the names of London districts while rarely sharing any accepted boundaries of those places. London postcode districts often have an influence over where a place is considered to be although they were not designed for that purpose.
