An election to Monaghan County Council took place on 23 May 2014 as part of that year's Irish local elections. 18 councillors were elected from three electoral divisions by PR-STV voting for a five-year term of office, a reduction of 2 seats compared to 2009. Monaghan also saw a further reduction in elected representation as Ballybay Town Council, Carrickmacross Town Council, Castleblayney Town Council, Clones Town Council and Monaghan Town Council were all abolished.
