The North Sea Jazz Festival is an annual festival held each second weekend of July in the Netherlands at the Ahoy venue. It used to be in The Hague but since 2006 it has been held in Rotterdam. This is because the Statenhal where the festival was held before was demolished in 2006. As of 3 November 2017 the festival officially will be known as the NN North Sea Jazz Festival.
