List of parliamentary constituencies in London 1950-1974

This is a list of parliamentary constituencies in London from 1950-1974.

Fundamental changes in parliamentary constituencies were made by the Representation of the People Act 1948, with the new boundaries first used in the 1950 general election.

The 1948 legislation replaced the previous terminology of "parliamentary boroughs" and "parliamentary counties" (and their single-member divisions) with the terms "borough constituency" and "county constituency". The act also abolished plural voting and the business vote. This particularly effected the City of London which had a very small resident population so that it had insufficient voters to remain a separate constituency. The legislation (and all subsequent electoral acts) provided that the city must be included in a single constituency which should have "City of London" in its title.

There was a review of constituencies in the Metropolitan Boroughs of Fulham and Hammersmith in 1955, with the four constituencies reduced to three.
