Askim is a town and the largest population center in Indre Østfold municipality, located in Østfold County, southeastern Norway. Originally established as a separate municipality on January 1, 1838, under the formannskapsdistrikt system, it merged into the larger Indre Østfold municipality in 2020 as part of a national administrative reform. Recognized as a city since 1996, Askim serves as a regional hub for nine surrounding municipalities, blending industrial heritage with modern amenities. It is positioned along the Glomma River, Norway's longest river, and functions as an important crossroads for transportation and commerce in the Indre Østfold region. With a population of approximately 15,368 as of 2024, Askim exemplifies a compact urban area that has grown steadily, reflecting a 9% increase over the previous decade up to 2014, though recent figures indicate stabilization.
Askim is situated at coordinates 59°35′10″N 11°10′12″E, covering a total area of 69 square kilometers, of which 66 square kilometers is land, ranking it as the 409th largest municipality by area in Norway prior to its merger. The town lies adjacent to the Glomma River, which forms natural borders with neighboring areas such as Spydeberg to the north and west, Skiptvet to the south, Trøgstad to the northeast, and Eidsberg to the southeast. This riverside location contributes to a landscape dominated by waterways, with three major waterfalls—Solbergfoss, Kykkelsrudfoss, and Vammafoss—harnessed for hydroelectric power. The terrain is relatively flat and fertile, supporting agriculture, while the population density stands at around 225 inhabitants per square kilometer. Askim's proximity to Oslo, about 60 kilometers southeast, places it within the broader Oslo metropolitan influence, offering a mix of rural charm and urban accessibility. The official language is Bokmål, and residents are known as Askiming.
Askim's history is marked by its strategic position along the Glomma River, which has facilitated trade and conflict crossings for centuries. The name derives from Old Norse "Askheimr," meaning "home of the ash trees," referencing the site of the area's first church built around 1200. Askim Rectory traces back to the 12th century, coinciding with the construction of the first stone church dedicated to the Virgin Mary. The town gained prominence during the Napoleonic Wars; on August 9, 1814, it hosted the last battle between Norwegian and Swedish forces at the Glomma crossing, ending the brief Norwegian-Swedish War and leading to the Union of Sweden and Norway. A yearly historical reenactment commemorates this event, alongside a stone monument at Langnes. During World War II, Askim was the site of a significant engagement at Fossum Bridge in April 1940, where Norwegian forces defended against German invaders during the Norwegian Campaign. Industrial development surged in the 20th century, including nickel mining at Romsåsen around 1900, known for unique "Spheroidal Norite" or "Potato Stone" formations. The coat-of-arms, granted in 1963, symbolizes the river's waterfalls and hydroelectric importance. In recent decades, Askim transitioned from a standalone municipality to part of Indre Østfold in 2020, reflecting ongoing administrative consolidations.
Askim's population was estimated at 15,368 in 2024, making it the 71st most populous urban area in Norway and the largest in Indre Østfold.

Askim's demographics reflect a blend of native Norwegians and newcomers, supporting a vibrant local economy.
Askim has long been an industrial hub, particularly in the 20th century, with a focus on manufacturing and energy production. The Glomma River powers three hydroelectric plants—Solbergfoss, Kykkelsrud, and Vamma—generating substantial electricity and contributing to Norway's renewable energy sector. Historical industries included nickel mining at Kykkelsrud and Romsåsen, and rubber production by Viking Gummi, which manufactured boots and tires until its closure in 1991 after acquisition by Continental Tyres. Today, Glava, a producer of glass wool insulation, stands as the primary employer, emphasizing sustainable materials. The broader economy ties into Norway's national strengths in energy, with Askim benefiting from state-owned sectors in natural resources. Commerce includes retail at the local shopping center, supported by the town's role as a regional center. Challenges include adapting to global shifts, but hydroelectric assets ensure economic stability.
Askim's connectivity is enhanced by European route E18, a major four-lane highway upgraded in 2005 to bypass the city center, reducing congestion while linking to Oslo and beyond. The Eastern Østfold Line railway, operated by Vy, serves the area with stations at Langnes, Næringsparken, and Askim, providing hourly trains for commuters. This infrastructure supports regional travel, with the train station integrated into the town's amenities, facilitating access to shopping and services.
