A referendum on joining the European Union was held in Norway on 27 and 28 November 1994.

Membership of what was then the European Community had previously been rejected in a 1972 referendum, and by French veto in 1962.

The "No" campaign was led by Anne Enger Lahnstein, leader of the Centre Party.

Unlike Trygve Bratteli in 1972, she refused to threaten to resign if the referendum failed to result in a "Yes" vote, on the grounds that more serious divisions could have arisen in the Labour Party.

According to John Erik Fossum, a political science professor at ARENA, Centre for European Studies, University of Oslo, "the fact that Norway had already signed the EEA agreement made it easier for people to vote no because they knew that Norway had assured EU market access.
