Mayo South was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas from 1923 to 1969. The method of election was the single transferable vote form of proportional representation (PR-STV).

The constituency was created under the Electoral Act 1923 for the 1923 general election to Dáil Éireann, whose members formed the 4th Dáil.

From 1923 to 1948, Mayo South elected 5 deputies (Teachtaí Dála, commonly known as TDs). Under the Electoral (Amendment) Act 1947, this was reduced to 4 with effect from the 1948 general election.

It was abolished under the Electoral (Amendment) Act 1969, when it and Mayo North were replaced by the two new constituencies of Mayo East and Mayo West.

The constituency covered the county electoral areas of Castlebar, Claremorris and Westport, in the administrative county of Mayo.
