The 1991 Irish local elections were held in all administrative counties and county boroughs on Thursday, 27 June 1991.

There was a second tier of boroughs, urban districts and towns with boards of commissioners.

[1] This allowed the Local Government Act 1991 to be passed beforehand.

Elections in non-county boroughs and towns were postponed until 1994.

[2] They were the first local elections contested by the Progressive Democrats, which had been founded in December 1985, and the first since Sinn Féin registered as a political party in December 1986.
