A Fingal County Council election was held in Ireland on 23 May 2014 as part of that year's local elections. Forty councillors were elected from a field of 97 candidates for a five-year term of office from five local electoral areas by proportional representation with a single transferable vote. Fingal County Council was expanded from 24 seats to 40 in recognition of population growth. Fianna Fáil emerged as the largest party after the elections with 7 seats with 3 net gains and securing 2 seats in each of Castleknock and Swords. Fine Gael retained 6 seats though found themselves without representation in Swords while securing 2 in each of Castleknock and Howth-Malahide. Sinn Féin also secured 6 seats, including 2 seats in Mulhuddart. Labour had a very bad election winning just 4 seats and losing 5 seats as a whole as well as being wiped out in Castleknock. The Anti-Austerity Alliance also made 4 gains, including 2 seats in Mulhuddart, chiefly coming from their former base in the Socialist Party. The Green Party returned to the Council Chamber with 2 seats in each of Castleknock and Howth-Malahide. People Before Profit also secured a seat in the Balbriggan LEA. Independents were however the chief winners in Fingal gaining 8 additional seats to emerge after the elections with a total of 10 seats.
