1920 Dublin Corporation election
An election to Dublin Corporation took place on Thursday, 15 January 1920 as part of the 1920 Irish local elections. Dublin was divided into ten borough electoral areas to elect 80 councillors for a five-year term of office on the system of proportional representation by means of the single transferable vote.
Sinn Féin won a slight majority in the council, with 42 seats. Whilst the Sinn Féin majority was small, they emerged from the election as by far the largest party on the Dublin Corporation council.
Following the election Thomas Kelly, the Sinn Féin MP for Dublin St Stephen's Green, was unanimously elected by the council as the new Lord Mayor of Dublin. Kelly was elected despite being held at the time as a political prisoner in Wormwood Scrubs prison in England. Kelly was nominated for the position by the outgoing Lord Mayor Laurence O'Neill. Due to Kelly's imprisonment O'Neill continued as effective Lord Mayor.

These were the first elections under the Local Government (Ireland) Act 1919, which introduced a form of proportional representation. Under the old ward system, each of 20 wards had elected one alderman and three additional councillors. In 1919, the Local Government Board of Ireland created 10 borough electoral areas, taking a greater account of population in the city, which took effect at these elections. Two councillors from each BEA were designated as aldermen.| BEA | Seats | Wards | Former representation |
