Allsång på Skansen is a Swedish show held at Skansen, Stockholm, every summer on Tuesdays between 8pm and 9pm. The audience is encouraged to sing along with musical guest stars to well-known Swedish and international songs. The show started in 1935 on a small scale; about 50 people in the audience. Today, about 10,000–25,500 people come to each performance.

Skansen is the oldest open-air museum and zoo in Sweden located on the island Djurgården in Stockholm, Sweden. It was opened on 11 October 1891 by Artur Hazelius (1833–1901) to show the way of life in the different parts of Sweden before the industrial era.
