The Magnetic Fields are an American band founded and led by Stephin Merritt. Merritt is the group's primary songwriter, producer, and vocalist, as well as frequent multi-instrumentalist. The band is named after the André Breton/Philippe Soupault novel Les Champs Magnétiques.

The band released their debut single "100,000 Fireflies" in 1991. The single was typical of the band's earlier career, characterized by synthesized instrumentation by Merritt, with lead vocals provided by Susan Anway (and then by Stephin Merritt himself, from the House of Tomorrow EP onwards). A more traditional band later materialized; it is now composed of Merritt, Claudia Gonson, Sam Davol, and John Woo, with occasional guest vocals by Shirley Simms. The band's best-known work is the 1999 three-volume concept album 69 Love Songs. It was followed in the succeeding years by a "no-synth" trilogy: i (2004), Distortion (2008), and Realism (2010). The band's latest album, Quickies, was released on May 29, 2020.
