Amager (Danish pronunciation: [ˈɑˌmɑˀ] or, especially among older speakers, [ˈɑˌmɛˀɐ]), located in the Øresund, is Denmark's most densely populated island, with more than 216,000 inhabitants (January 2022).

In 1521, Christian II invited some Dutch farmers to move to Amager and grow vegetables to supply the Danish Court and Copenhagen.

Due to this and a ban on mixed marriages, they maintained their own language, Amager Dutch, which remained spoken until 1858.

During the Second World War, high unemployment in Copenhagen led authorities to drain a large part of the sea, west of the island, and build a dam to hold out the water, effectively adding one half of Amager's previous area to the island.

Large parts of Kalvebod Fælled are rich in nature and have many grazing cows and horses.

Top bands from the last 40 years have played there, both those of international origin (Prince, Alien Ant Farm, P.O.D, Aimee Mann, Uriah Heep, King Crimson, Cradle of Filth, John Mayall and the Bluesbreakers, Jethro Tull, The Moody Blues, MGMT, Nas, Andrew Bird) and from Denmark (D.A.D, Dodo and the Dodos, Johnny Deluxe, Big Fat Snake).

The former military area is home to a diverse range of flora and fauna; including forests, fields, and Highland cattle.

[3] The King's Grove (Danish: Kongelunden) is a large oak forest located on the southern side of Amager.

[6] Various communities are located on Amager, including Islands Brygge, and the towns of Dragør, Kastrup, and Tårnby.
