Kalundborg (Danish: [kʰælɔnˈpɒˀ]) is a Danish city with a population of 16,558 (1 January 2024), the main town of the municipality of the same name and the site of its municipal council. It is situated on the northwestern coast of the largest Danish island, Zealand (or Sjælland in Danish), on the opposite, eastern side of which lies the capital Copenhagen, 110 km (68 mi) away. Kalundborg is famous as the location of a large broadcasting facility, the Kalundborg Transmitter. The city was also home to the largest coal-fired power station in Denmark, the Asnæs Power Station, which started its transition to biomass in 2017. Kalundborg is mainly a trading and industrial town, but is also well known for its five-spired Church of Our Lady, which is closely associated with King Valdemar I and the Archbishop Absalon. The church itself is said to have been built by Absalon's brother, Esbern Snare. Kalundborg is also the traditional seat of the aristocratic Lerche family. Their stately home, Lerchenborg, the best example of rococo architecture in Denmark, can be seen in the town's outskirts. Ferries connect Kalundborg westward to the island of Samsø.

The Siege of Kalundborg (Danish: Belejringen af Kalundborg), also known as the Siege of Kalundborg Castle, was a siege by Valdemar IV of Denmark on the Norwegian-pledged Kalundborg Castle in 1341 during the Kalundborg War, which is named after the siege. The Danes were forced to retreat after a surprise attack on the Danish camp by Henry II, Count of Holstein-Rendsburg.

The Church of Our Lady (Vor Frue Kirke, Kalundborg) is a historical building at Kalundborg in northwestern Zealand, Denmark. The precise date of construction is not known with any certainty, though its architecture indicates the early part of the 13th century. With its five distinctive towers, it stands on a hill above the harbour, making it the town's most imposing landmark.

Kalundborg Municipality (Danish: Kalundborg Kommune) is a kommune in the Region Sjælland on the west coast of the island of Zealand in Denmark. The municipality covers an area of 604 km2 (233 sq mi), and has a total population of 48,309 (1. January 2024). Its mayor is Martin Damm, a member of Venstre. The main town and the site of its municipal council is the city of Kalundborg. The municipality is surrounded by water on three sides: Samsø Bælt— the strait which separates the municipality from the island of Samsø— and Sejerø Bay (Sejerø Bugt) — the bay in which the island of Sejerø is located) to the north The Great Belt (Storebælt)— the strait which separates Zealand from the island of Funen) and the Kattegat to the west Jammerland Bay (Jammerland Bugt) to the south. The municipalities of Samsø to the northwest, and Juelsminde on the Jutland peninsula to the west are thus also Kalundborg's municipal neighbors, albeit separated by water. Ferry lines connect the municipality to Aarhus on the Jutland peninsula, and to the island of Samsø at the central harbour in Kalundborg. The harbour is conveniently located near the Kalundborg train station, which connects to the cities of Holbæk and Copenhagen. A large industrial zone, including a South Harbour?, is located south of the town's central area. On January 1, 2007 Kalundborg municipality was, as the result of Kommunalreformen ("The Municipal Reform" of 2007), merged with existing Gørlev, Hvidebæk, Bjergsted, and Høng municipalities to form the new Kalundborg municipality.

The Asnæs Power Station (Danish: Asnæsværket) is a woodchip power plant operated by Ørsted A/S in Kalundborg, Denmark. It consists of three active units, which deliver 147 MW (Unit 2), 270 MW (Unit 4) and 640 MW (Unit 5). Unit 3 went in service in 1959 and uses a 152.1-metre-tall (499 ft) flue gas stack, while Unit 5, which went into service in 1981, uses a 220.1-metre-tall (722 ft) flue gas stack, the third tallest in Denmark. Its two 60m high coal cranes were dismantled in 2016.

Kalundborg Eco-Industrial Park is an industrial symbiosis network located in Kalundborg, Denmark, in which companies in the region collaborate to use each other's by-products and otherwise share resources. The Kalundborg Eco-Industrial Park is the first full realization of industrial symbiosis. The collaboration and its environmental implications arose unintentionally through private initiatives, as opposed to government planning, making it a model for private planning of eco-industrial parks. At the center of the exchange network is the Asnæs Power Station, a 1500MW coal-fired power plant, which has material and energy links with the community and several other companies. Surplus heat from this power plant is used to heat 3500 local homes in addition to a nearby fish farm, whose sludge is then sold as a fertilizer. Steam from the power plant is sold to Novo Nordisk, a pharmaceutical and enzyme manufacturer, in addition to Statoil oil refinery. This reuse of heat reduces the amount thermal pollution discharged to a nearby fjord. Additionally, a by-product from the power plant's sulfur dioxide scrubber contains gypsum, which is sold to a wallboard manufacturer. Almost all of the manufacturer's gypsum needs are met this way, which reduces the amount of open-pit mining needed. Furthermore, fly ash and clinker from the power plant is used for road building and cement production. These exchanges of waste, water and materials have greatly increased environmental and economic efficiency, as well as created other less tangible benefits for these actors, including sharing of personnel, equipment, and information.
