Parliamentary elections were held in Norway on 7 October 1957. The result was a victory for the Labour Party, which won 78 of the 150 seats in the Storting. As a result, the Gerhardsen government continued in office.
This was the last time a single party won a majority of seats on its own in a Norwegian election. This was also the last Norwegian parliamentary election as of 2026 to not be held in September.
