Norrland (Swedish: [ˈnɔ̌rːland] ^ⓘ, lit. 'Northland', originally Norrlanden, meaning 'the Northlands') is the northernmost, largest and least populated of the three traditional lands of Sweden, consisting of nine provinces. Although Norrland does not serve any administrative purposes, it continues to exist as a historical, cultural, and geographic region; it is often referred to in everyday language, e.g., in weather forecasts. Several related Norrland dialects form a distinct subset of dialects of the Swedish language separate from those to its south.

Norrland consists of the majority of the Swedish landmass at about 60% of the land area, but only has about 12% of the country's population. Its largest city is Umeå, while the other four county seats are Gävle, Härnösand, Östersund and Luleå. The largest non-capitals are Sundsvall, Skellefteå and Örnsköldsvik while Kiruna is the largest town of the vast Lapland province in the far north. Sweden's highest mountain Kebnekaise and deepest lake of Hornavan are in Norrland. Plenty of long rivers originating in the mountains run through the Norrland forests, with major coastal towns frequently being on their estuaries. Their extensive drops in elevation also make Norrland a major producer of hydroelectricity from some of those rivers.

Winters in Norrland are cold by Swedish standards but mild for the latitudes. The vastness of the region renders very different environments and climates, ranging from mild coastal climates of Gävleborg to the tundra climate of the high mountains. In general, the most common climate is the subarctic type. The cold climate has led to winter sports being popular, with Norrland teams and athletes being especially successful in ice hockey, skiing and bandy.

Norrland comprises the historical nine provinces (landskap):

Historically, Jämtland and Härjedalen belonged to Norway until 1645, and are thus often considered outside of the historical Norrland. On the other hand, Finland belonged to Sweden until 1809, and during that time, Norrland was extended into Northern Finland. Administratively, Sweden is not divided into provinces but into counties (län). Although Norrland is defined in terms of the historical provinces and not the counties, it roughly comprises the modern counties of Gävleborg, Jämtland, Norrbotten, Västerbotten and Västernorrland.

Sometimes, Norrland is subdivided into Northern Norrland (norra Norrland) and Southern Norrland (södra Norrland). The northern part of the region typically covers the historical provinces of Norrbotten, Västerbotten and Lappland (the modern counties of Norrbotten and Västerbotten), while the southern part covers the remainder of the region. There is also the concept of Middle Norrland (mellersta Norrland), which is the northern part of Southern Norrland. Middle Norrland has no clearly defined boundaries, but usually corresponds with the historical provinces Ångermanland, Medelpad, Jämtland and Härjedalen.

Except for the coastal areas, Norrland is sparsely populated. Approximately 12 percent of Sweden's population lives in Norrland. Except for some coastal areas most of Norrland is made up by the Norrland terrain—hilly and mountainous land covered by boreal forests. More in detail Norrland is made up of three north–south belts: the Scandinavian Mountains in the west, the Muddus Plains covering much of the inland, and the mixed relief of the eastern coast.

Unlike the much more densely populated Svealand and Götaland, which are better known for big cities (Stockholm, Gothenburg, Malmö) with landmarks and tourist attractions, Norrland is known for its nature with wide forests, large rivers and untouched wilderness.
