No-Fi Soul Rebellion is an American musical group formed in Alaska in 2001. The band was started by Mark Heimer, who records all vocals and music himself. The performing band is made up Mark Heimer and his wife Andrea Heimer. The couple was based in Seattle for a time and now resides in Bellingham, WA.

No-Fi Soul Rebellion is most noted for their dynamic, unconventional live shows, which feature the band performing on the venue floor in the middle of the audience. Mark Heimer uses a 50-foot-long (15 m) microphone cord, giving him enough movement space to dance and sing directly to most members of the audience. Andrea Heimer provides backing vocals and plays backing tracks through an MP3 player housed inside a non-working electric guitar, known as "The Soul System."
