Mary Mary is a Grammy Award-winning American contemporary gospel duo, consisting of sisters Erica Atkins-Campbell (born April 29, 1972) and Trecina "Tinkins-Campbell (born May 1, 1974). The duo are often credited along with Kirk Franklin for broadening the fan base of urban contemporary gospel in the 2000s by introducing elements of soul music, hip hop, funk and jazz. Mary Mary broke onto the music scene with their popular song "Shackles (Praise You)"—which is considered one of the pioneering songs of urban contemporary gospel music. The group's name, as stated in an interview is inspired by the two famous Marys from the Bible; Mary, the mother of Jesus Christ, and Mary Magdalene.

Their debut album, Thankful (2000), was certified Platinum. In addition, the duo has released two Gold albums: Incredible (2002) and Mary Mary (2005), both of which have charted at No. 1 on the Billboard Top Gospel Albums. They have also received four Grammys, among other awards. In 2011, they released their fifth studio album, Something Big.

In March 2012, they premiered their own television series, Mary Mary, on WE tv. A second season premiered in December 2012 and concluded in February 2013. Their most recently released album is their first compilation album, Go Get It (2012), with the hit single of the same name. Then the third season premieres on February 27.
