County Offaly 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 Birr, Edenderry and Tullamore were all abolished.

Fianna Fáil remained the largest party after the elections winning 8 seats.

Sinn Féin won 3 seats and in terms of vote share also became the second largest party.

Fine Gael, by contrast, had a poor set of results and lost half of their seats.
