South is a European Parliament constituency in Ireland. It elects 5 Members of the European Parliament (MEPs) using proportional representation by means of the single transferable vote (PR-STV).

It was created in 2004 with the same area as the old Munster constituency, except for County Clare which was then in North-West.^[1] It is sometimes referred to as Ireland South.^[2] The area of the constituency has increased twice.

For the 2019 European Parliament election, a reapportionment following Brexit and the loss of 73 MEPs from the United Kingdom gave two additional seats to Ireland. Following a recommendation of the Constituency Commission, South gained territory and an additional seat, from 4 to 5.^[3][4][5] However, Deirdre Clune, as the last candidate elected, did not take her seat until after the United Kingdom left the European Union.^[6]

In 2016, 74.1% of the constituency's population lived in Munster, while the southern Leinster counties accounted for 25.9%.^[7][8]

It comprises the counties of Carlow, Clare, Cork, Kerry, Kilkenny, Laois, Limerick, Offaly, Tipperary, Waterford, Wexford, and Wicklow; the cities of Cork, Limerick, and Waterford.^[5]

The main urban areas (by population size) are Cork, Limerick, Waterford, Bray, Kilkenny, Ennis, Carlow, Tralee, Tullamore, Portlaoise, and Wexford.
