A referendum on joining the European Community was held in Norway on 25 September 1972.

After a long period of heated debate, the "no" side won with 53.5% of the vote.

Prime Minister Trygve Bratteli, who had championed a "yes" vote, resigned as a result.

This was Norway's second attempt at becoming a member, after having been vetoed by France in January 1963 and again temporarily in 1967, but the first attempt with a referendum on a set of fully negotiated accession terms.
