The N (Northern) postcode area, also known as the London N postcode area, is the part of the London post town covering part of North London, England.

It includes areas in the London boroughs of Hackney, Islington, Camden, Barnet, Haringey and Enfield. The N postcode area does not cover all of the north of Greater London however. For example, parts of the London Borough of Enfield and the London Borough of Barnet are covered by the EN postcode area, and parts of the London Borough of Barnet and the London Borough of Camden are covered by the NW postcode area.

The postcode area originated in 1857 as the N district of London. In 1917 it was subdivided into 22 numbered districts. The Northern head district was designated as N1 and the rest of the numbering followed the alphabetical order of the other districts' main names. Most districts include local areas known by their own specific names (see table below). The official post town for all N postcodes is LONDON; district names do not form an essential part of postal addresses.
