South Mayo was a parliamentary constituency in Ireland, which returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom, elected on a system of first-past-the-post, from 1885 to 1922.

Prior to the 1885 general election the area was part of the two-seat Mayo constituency. From 1922, on the establishment of the Irish Free State, it was not represented in the UK Parliament.
