Hardenberg (Dutch: [ˈɦɑrdə(m)bɛr(ə)x] ; Dutch Low Saxon: Haddenbarreg or 'n Arnbarg) is a city and municipality in the province of Overijssel in north-eastern Netherlands. It has borders with the province of Drenthe and an international German border. The population of Hardenberg municipality is 63,895 (in 2025). Other than Hardenberg itself, the second largest population center is Dedemsvaart, and Gramsbergen is the only other city in the municipality.
The city of Hardenberg received city rights in 1362 and today has 20.285 inhabitants. It is located to the south-west of Coevorden, south-east of Hoogeveen, and north of Almelo. The Vecht river flows through it and the municipality (together with Ommen and Dalfsen) makes up the Vechtdal (Vecht Valley) area. A sizable portion of the population speaks Dutch Low Saxon as a native language.
The municipality Hardenberg was formed on 1 May 1941 during the Reichskommissariat Niederlande period from merging Stad Hardenberg with Ambt Hardenberg, which was headquartered in Heemse. In January 2001, the municipalities Avereest and Gramsbergen were merged into Hardenberg to form a new, larger municipality.

History
Around the year 760, the village of Nijenstede is said to have originated just east of the present-day center of Hardenberg , where, according to Johan Picardt, the Frankish steward Pepin the Short built a chapel.
In 1227, the bishop of Utrecht Otto II of Lippe was defeated and killed during the Battle of Ane by Rudolph van Coevorden, who led a Drenths rebellion. Because of this, the new bishop Wilbrand of Oldenburg built a castle to the west of Nijenstede called Hardenberch (or Herdenbergh/Hardenborch) in 1230, protected to the north and west by the Vecht and on other sides by dugged moat.
Bishop John of Arkel replaced the castle with a new fortress in 1354. Four years later, he had the castle mound leveled, creating space for the construction of an oval stone wall around the castle, complete with towers and blockhouses. The resulting fortress measured 125 by 60 meters. This proved large enough to accommodate residents, and more and more inhabitants moved from Nijenstede to the safe haven of Hardenberg, creating a new town. In 1362, Bishop Arkel transferred Nijenstede's old rights and privileges to this new settlement, Hardenberg, and also granted it city rights. Two years later, Emperor Charles IV authorized the establishment of a toll in Hardenberg. The toll revenues enabled the maintenance of the Hardenberg fortress, which guarded the borders of Overijssel.
In 1386, the castle was further fortified and embellished. The town also received a new wall. On 5 March 1497, Hardenberg was almost entirely destroyed by a fire. Gramsbergen received city rights in 1442.
In the 15th century, Hardenberg was no longer mentioned as a border fortress. It likely become redundant due to nearby Coevorden and the defenses at Venebrugge and Brucht. Hardenberg did, however, continue to serve as the bishop's residence. In 1518, Bishop Philip of Burgundy ordered the demolition of Hardenberg castle and the fortress wall as well. Since 1959, sections of the old fortress wall have been uncovered and preserved. The Höftekerk now stands on the site where the castle once stood.
On 18 May 1708, a woman named Aaltje Kraak accidentally caused a fire that destroyed almost all of the city of Hardenberg. The hundred wooden houses that made up the town were almost all destroyed. The town was rebuilt with stone houses after a national fundraising campaign.
