"Wanderlust" is a song written and recorded by Icelandic singer Björk. The track was released digitally as the fourth single from her seventh full-length studio album, Volta, on 7 April 2008.

White labels of the single were issued in February 2008. The physical single was released on 12 June after an almost two-month delay.

Björk has described "Wanderlust" as being the heart of Volta, and has said that the song is about "the state of looking for something and almost knowing you're never going to find it" and that it makes fun of her hunger for "something new". It was released in the UK on 30 June.

As Björk said in an interview for Harp, "Things go in circles. Wanderlust, for example, is a sort of continuity of 'Hyperballad'."

Björk has performed the song during every show of her Volta Tour. She also performed the song on Saturday Night Live on 21 April 2007 and on Late Night with Conan O'Brien on 27 September 2007. The 3D version of the music video was premiered as part of the 19 April Record Store Day in the United States, an event celebrating the independent record store culture. Over 10,000 pairs of 3D glasses were distributed for home viewing as well as selected in-store video kiosk locations.

The music video, directed by Isaiah Saxon and Sean Hellfritsch of Encyclopedia Pictura in New York City in stereoscopic 3D, involves a mixture of large scale puppeteering, live-action acrobatics, miniatures, and CG. The video took nine months to complete and required the creation of a custom-built 3d camera system. It was choreographed by Chris Elam, artistic director of Misnomer Dance, and features Brynne Billingsley and Coco Karol. The video features an unusual style of pillarboxing where the inside edges are concave. It officially premiered on Yahoo Music on 31 March. In the video, a group of yaks crowd beside a river bank. Björk, in an ancient Mongolian tribal costume, appears amongst them and creates a river from the ground. She rises up and leads the herd into the river, and they all float downstream, with Björk on the back of one of the yak-like creatures. Throughout the video, a clay personal demon, dubbed the "painbody" by the directors, comes out of her backpack and tries to attack her. Finally, a god creates a waterfall and Björk falls off the edge and into the water below, where a pair of hands catches her after a vortex of water has engulfed her and the painbody.
