An election to Wicklow County Council took place on 27 June 1991 as part of that year's Irish local elections.

24 councillors were elected from five local electoral areas (LEAs) for a five-year term of office on the electoral system of proportional representation by means of the single transferable vote (PR-STV).

This term was extended twice, first to 1998, then to 1999.
