2001 Irish constitutional referendums

Three referendums were held simultaneously in Ireland on 7 June 2001, each on a proposed amendment to the Constitution of Ireland. Two of the measures were approved, while the third was rejected. The two successful amendments concerned the death penalty and the International Criminal Court.

The failed amendment concerned the Treaty of Nice. It has also been intended to submit a fourth proposal to a referendum, concerning the investigation of judges, but this amendment was not ultimately passed by the Oireachtas (parliament) and so was never put to a vote.
