Northwest Territories Legislative Building, Government building in Yellowknife, Canada

The Northwest Territories Legislative Building is a two-story structure on Frame Lake in Yellowknife, completed in 1993. It has two round halls, the Great Hall and the Caucus Room, and is clad in zinc panels, a material mined in the Territories. Inside, maple ceilings and slate floors are used, and the Great Hall's floor-to-ceiling windows face a treed forecourt.

Queen Elizabeth II opened the building in 1994, marking a turning point for territorial governance after years of administration from other locations. This opening symbolized a new era of local self-determination and representation for the Northwest Territories.

The chamber and Caucus Room are circular to support consensus-style government, with members seated without party divisions. Translation booths around the chamber carry simultaneous interpretation in the territories' 11 official languages. A translucent glass frieze by Warren Carther of Winnipeg and Angus Cockney of Yellowknife diffuses daylight into the room, and a hand-worked zinc wall behind the Speaker's Chair, made with artists Letia Lewis and John Farcey Jr., echoes nearby rock formations.

The building stands on the shore of Frame Lake, set between Canadian Shield rock outcrops, a peat bog and existing trees. The Great Hall's floor-to-ceiling windows face a treed forecourt, and opening vent panels in each member's office let occupants control fresh air. Public tours of the legislative spaces were offered in earlier premises, so check the current assembly schedule before visiting.

The polar bear hide on the assembly table is a replacement. The original, on loan from the Hudson's Bay Company collection in Winnipeg, was stolen one night in early August 1985 from the Yellowknife Inn, where the Assembly then met. Thieves left the narwhal tusk and other pelts behind; the hide, valued at CAN$10,000–15,000, was never recovered. Ludy Pudluk, then MLA for the High Arctic, donated the current one when the building opened in 1993.
