Norwegian European Communities membership referendum, 1972

A referendum on whether Norway should join the European Community was held on 25 September 1972. After a long period of heated debate, the "No" side won with 53.5 per cent of the vote. Prime Minister Trygve Bratteli resigned as a result of the defeat. This was Norway's second attempt at becoming member, after having been rejected by France in 1962 and again temporarily in 1967, but the first attempt with a referendum on a set of fully negotiated accession terms.

A 1994 referendum on entry into what had become the European Union also resulted in the rejection of membership.
