An election to Westmeath County Council took place on 27 June 1991 as part of that year's Irish local elections. 23 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.[1] [2]
