Borgen (Danish pronunciation: [ˈpɒˀwn̩]) is a Danish political drama television series. Adam Price is the co-writer and developer of the series, together with Jeppe Gjervig Gram and Tobias Lindholm. Borgen is produced by SAM Productions on behalf of DR, the Danish public broadcaster, which previously produced The Killing. In Denmark, "Borgen" (lit. 'The Castle') is the informal name of Christiansborg Palace where all three branches of Danish government reside: the Parliament, the Prime Minister's Office, and the Supreme Court, and is often used as a stand in term for the Danish Parliament (Folketinget).

The programme tells how, against all the odds, Birgitte Nyborg Christensen (Sidse Babett Knudsen)—a minor centrist politician—becomes the first female prime minister of Denmark. Other main characters are Birgitte Hjort Sørensen as Katrine Fønsmark, a TV1 news anchor; Pilou Asbæk as Kasper Juul, a spin doctor; Søren Malling as Torben Friis, news editor for TV1; Mikael Birkkjær as Birgitte's husband, Phillip; and Benedikte Hansen as Hanne Holm, a journalist.

The first season of Borgen premiered in Denmark on 26 September 2010. Two more seasons, each also ten episodes long, followed in September 2011 and January 2013. Nine years later, in February 2022, the eight-episode-long fourth season (subtitled Power & Glory) was released in collaboration with Netflix.
