East Ham South was a parliamentary constituency centred on the East Ham district of London, which was in Essex until 1965. It returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom, elected by the first past the post voting system.
The constituency was created by the Representation of the People Act 1918 for the 1918 general election. It was abolished for the February 1974 general election.
