Grace Potter and the Nocturnals is an American rock band from Vermont. Formed in 2002 in Waitsfield by drummer Matt Burr, guitarist Scott Tournet, and singer Grace Potter, they began their career as an indie band, self-producing their albums and touring extensively in the jam bands and music festivals circuit, playing as many as 200 gigs in a year. In 2005 they signed for Hollywood Records; they have published four studio albums, encompassing rock subgenres such as blues rock, folk rock, hard rock, and alternative rock. Their third, self-titled album (2010) has been a major commercial success, topping iTunes charts and receiving international attention.

The band is fronted by lead vocalist and multi-instrumentalist Grace Potter (born June 20, 1983), who is known for her vocal qualities—evocative of blues rock singers like Janis Joplin or Koko Taylor—as well as for her vibrant energy on stage. Besides playing with the Nocturnals, Potter has also released solo material and collaborated with other artists.
