Eric Ericsons Kammarkör is a Swedish professional chamber choir formed in Stockholm in the 1960s, specialising in a cappella choral repertoire across a range of historical periods. Their repertoire spans Renaissance polyphony through Romantic and 20th–21st-century works with a particular emphasis on contemporary Scandinavian compositions, and the ensemble has contributed to the development of Sweden's choral performance practice and the international profile of Scandinavian choral music.
