PureNRG (pronounced "Pure Energy") was a Christian pop group from Nashville, Tennessee. They were signed to Fervent Records in late 2006. They released six albums: their self-titled debut (May 2007), Here We Go Again (April 2008), A PureNRG Christmas (September 2008), ReNRGized, a remix album (December 2008), The Real Thing (July 2009), and Graduation: The Best Of PureNRG (July 2010).

The group had three members: Caroline Williams, Laura Carolyne Myers, and Jordan Yates. Their road manager was Brandon Hargest, formerly of the teen pop group Jump5. Caroline and Laura (who goes by Carolyne) met when they were three and attended the same dance class. Jordan became a friend later through him being in their older siblings' dance classes. The group was formed after they went to auditions being held by their management company. After winning, they signed with Fervent Records and started writing songs. They were featured opening acts on the Winter Jam 2008 and 2009 tours and with Jump5 for Jump5's farewell tour in which they performed songs from their first album.

Their self-titled debut album spawned 3 singles: "360", "What If", and "Footloose". "Footloose" received heavy radio play on Radio Disney and other Pop format radio stations. In 2008, they released their second album, Here We Go Again, which featured covers of songs like "Call On Jesus" by Nicole C. Mullen and "More" by Matthew West.

In 2009, their last studio album, The Real Thing, was released. The band decided to disband sometime in late 2010. They went on a farewell tour in the fall of 2010. All of the members said they were very sad to be disbanding, but they felt that God was calling them out. Caroline Williams went on to join iShine.
