The Storting (Norwegian: Stortinget [ˈstûːʈɪŋə]; lit. 'the Great Thing') 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".

The assembly is led by a president and, since 2009, five vice presidents: the presidium. The members are allocated to twelve standing committees as well as four procedural committees. Three ombudsmen are directly subordinate to parliament: the Parliamentary Intelligence Oversight Committee and the Office of the Auditor General.

Parliamentarianism was established in 1884, with the Storting operating a form of "qualified unicameralism", in which it divided its membership into two internal chambers making Norway a de facto bicameral parliament, the Lagting and the Odelsting. Following a constitutional amendment in 2007, this was abolished, taking effect following the 2009 election.

Following the 2025 election, nine parties are represented in parliament: the Labour Party (53), the Progress Party (47), the Conservative Party (24), the Centre Party (9), the Socialist Left Party (9), the Red Party (9), the Green Party (8), the Christian Democratic Party (7), and the Liberal Party (3). Since 2021, Masud Gharahkhani has been President of the Storting.

The parliament in its present form was first constituted at Eidsvoll in 1814, although its origins can be traced back to the allting, as early as the 9th century, a type of thing, or common assembly of free men in Germanic societies that would gather at a place called a thingstead and were presided over by lawspeakers. The alltings were where legal and political matters were discussed. These gradually were formalised so that the things grew into regional meetings and acquired backing and authority from the Crown, even to the extent that on occasions they were instrumental in effecting change in the monarchy itself.

As oral laws became codified and Norway unified as a geopolitical entity in the 10th century, the lagtings ("law things") were established as superior regional assemblies. During the mid-13th century, the by then archaic regional assemblies, the Frostating, the Gulating, the Eidsivating and the Borgarting, were amalgamated and the corpus of law was set down under the command of King Magnus Lagabøte. This jurisdiction remained significant until King Frederick III proclaimed absolute monarchy in 1660; this was ratified by the passage of the King Act of 1665, and this became the constitution of the Union of Denmark and Norway and remained so until 1814 and the foundation of the Storting.

The Parliament of Norway Building opened in 1866.

On 27 June 1940 the presidium signed an appeal to King Haakon, seeking his abdication. (The presidium then consisted of the presidents and vice-presidents of parliament, Odelstinget and Lagtinget. Ivar Lykke stepped in (according to mandate) in place of the president in exile, C. J. Hambro; Lykke was one [of the six] who signed.)
