Luleå (/ˈluːleɪoʊ/ LOO-lay-oh,^[3] Swedish: [ˈlʉːlɛɔ] (listen), locally [ˈlʉːlɛ] (listen); Westrobothnian: Lul, Leul, or Leol [²lʉːɽ], locally [²lewɽ]; Lule Sami: Luleju) is a city on the coast of northern Sweden, and the capital of Norrbotten County, the northernmost county in Sweden. Luleå has about 75,000 inhabitants and is the seat of Luleå Municipality (with a total population of 76,770).

Luleå has the seventh biggest harbor in Sweden for shipping goods.^[4] It has a large steel industry and is a center for extensive research. Luleå University of Technology is one of Sweden's three technology universities (the other two are KTH and Chalmers) and the northernmost university in Sweden.

The town's Royal charter was granted in 1621 by King Gustavus Adolphus of Sweden. The original town was situated where Gammelstad (Old Town) is situated today. The town had to be moved in 1649 to the current site, due to the post-glacial rebound that had made the bay too shallow for ships to enter.

The Gammelstad Church Town is a UNESCO World Heritage Site.

In 1805, Luleå only had 947 inhabitants, but in 1865 Luleå succeeded Piteå as the county town in Norrbotten county and now had around 1400 residents. In the 1860s the industries also started taking root in the city.

The town has been plagued by fires in 1653, 1657 and in 1887, and the fire in 1887 was a devastating fire that destroyed most of the town, sparing only a few buildings. The Neo-Gothic Cathedral (originally the Oscar Fredrik church), dedicated in 1893, standing at 67 meters (220 ft), is the tallest building in town.

Luleå's commerce and industry are a mix of industry, research, education, trade, and services.

Major employers in the city are the SSAB steelworks and Luleå University of Technology. A Swedish Air Force wing, F 21 (or Norrbotten Air Force Wing), is stationed near Luleå at the neighbouring Luleå Airport. Other major employers include Ferruform (a subsidiary of Scania AB) and Gestamp HardTech (acquired from SSAB 2005-01-01).

Luleå is the home of several major innovations and technological milestones.^[5]
