Parliamentary elections were held in Norway on 11 September 2017 to elect all 169 members of the unicameral Norwegian Parliament, the Storting. The non-socialist parties retained a reduced majority of 88 seats, allowing Prime Minister Erna Solberg's Conservative-Progress coalition to remain in government. The Liberal Party joined the coalition in January 2018 but it remained a minority cabinet until the Christian Democratic Party joined the coalition in 2019. The three largest centre-left parties won 79 seats. The Green Party retained its single seat, while the Red Party won its first ever seat.

The Storting is the supreme legislature of Norway, established in 1814 by the Constitution of Norway. It is located in Oslo. The unicameral parliament has 169 members and is elected every four years based on party-list proportional representation in nineteen multi-seat constituencies. A member of the Storting is known in Norwegian as a stortingsrepresentant, literally "Storting representative".
