Wintergatan (Swedish pronunciation: [ˈvɪ̂nːtɛrˌɡɑːtan], "the Milky Way", lit.'"the Winter Street"') is a Swedish folktronica band from Gothenburg. Martin Molin and Marcus Sjöberg were previously part of the former band Detektivbyrån. The band uses a variety of unconventional instruments including the Modulin, a fingerboard-controlled synthesizer built from Doepfer eurorack modules, the Moog Theremini digital theremin, an electric autoharp, a hammered dulcimer, a self-built punch-card music box, a slide projector, a musical saw, and a typewriter for use as percussion.

The band's members all play various instruments, but have primary specializations. Martin Molin specializes in the vibraphone as well as the electronic instruments that define Wintergatan's sound; Evelina Hägglund specializes in keyboard instruments; David Zandén specializes in bass; and Marcus Sjöberg specializes in drums.

The band released their first track in late 2012, titled Sommarfågel, and released their debut album Wintergatan in 2013. The band toured with the album around Sweden in 2014 and 2016; Julia Jonas substituted for Evelina Hägglund during some 2014 performances.
