The Electoral (Amendment) Act 1995 (No. 21) was a law of Ireland which revised Dáil constituencies in light of the 1991 census. It took effect on the dissolution of the 27th Dáil on 15 May 1997 and a general election for the 28th Dáil on the revised constituencies took place on 6 June 1997. It adopted recommendations from an independent Commission chaired by Richard Johnson, judge of the High Court, which delivered its report on 27 April 1995. It repealed the Electoral (Amendment) Act 1990, which had defined constituencies since the 1992 general election.
