The Norwegian Student Choral Society (Norwegian: Den norske Studentersangforening) is a Norwegian male voice choir, founded in 1845 by Johan Diederich Behrens. It is the second oldest choir in Norway and the official choir of the University of Oslo.
Premiering a number of well known pieces, including Norway's national anthem "Ja, vi elsker dette landet", the choir is most commonly known for their yearly outdoor concert at University Square on 17 May, the Norwegian Constitution Day. The concert is broadcast live on NRK Radio.
The choirs' first official performance was at Henrik Wergeland's funeral.
Commonly referred to as "DnS" by members and friends, the choir holds regular concerts, both independently and in collaboration with other artists, choirs and orchestras.
