Mysteryland is the leading electronic dance music festival in the Netherlands,[1] organized by the Netherlands-based promoter ID&T.

Being the first of its kind in the country when it was established, its organizers have billed the event as the oldest dance music festival in the Netherlands.

It has most recently been held at Haarlemmermeerse Bos in Haarlemmermeer; an exhibition ground that hosted the 2002 edition of the Dutch gardening festival Floriade.

Mysteryland USA, the American version of Mysteryland, was first held on Memorial Day weekend, May 2014, at the Bethel Woods Center for the Arts, the site of the notable Woodstock festival held in 1969.

[2] Headliners included Kaskade, Moby, Steve Aoki, Dillon Francis, and Flosstradamus.
