2014 Monaghan County Council election

An election to all 18 seats on Monaghan County Council took place on 23 May 2014 as part of the 2014 Irish local elections, a decrease from 20 seats at the 2009 election. County Monaghan was divided into three local electoral areas (LEAs) to elect councillors for a five-year term of office on the electoral system of proportional representation by means of the single transferable vote (PR-STV). In addition, the town councils of Ballybay, Carrickmacross, Castleblayney, Clones and Monaghan were abolished.

New LEAs were introduced in 2013 and came into effect on 1 January 2014. The election in Ballybay–Clones local electoral area was halted when Fine Gael Councillor Owen Bannigan died suddenly while out canvassing on polling day. The election for this area was cancelled and all the ballots cast were officially destroyed. He had been expected to top the poll. It was re-run on 7 June 2014.

Sinn Féin emerged as the largest party with 7 seats, winning all the seats it contested. Fine Gael lost a seat in the Carrickmacross–Castleblayney LEA while Fianna Fáil lost a seat in Ballybay–Clones. Independents retained their 2 seats on the council.
