Mary Mary is an American contemporary gospel duo, consisting of sisters Erica Atkins-Campbell (born April 29, 1972) and Trecina "Tina" Atkins-Campbell (born May 2, 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 Mary's 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 three Gold albums: Incredible (2002), Mary Mary (2005), and The Sound (2008) which have all charted No. 1 on the Billboard Top Gospel Albums. They have also received three Grammys, among other awards. In 2011, they released their fifth studio album Something Big with the hit single "Walking".
In March 2012, they began their own television series, Mary Mary, on WeTV, which has been such a success that they are in the process of making a second season, which is due to begin in December 2012. Their most recently released album is their first compilation album, Go Get It (2012), with the hit single of the same name.
A meeting with producer Warryn Campbell led to their song publishing deal with the giant EMI music conglomerate and a series of songs that landed on movie soundtracks. They wrote "Dance" and performed it with Robin S. for the soundtrack to the 1998 film Dr. Dolittle; they performed "Let Go, Let God" for The Prince of Egypt. Several of their songs were recorded by 702. The sisters' profile in the gospel industry was raised when their songs "Time To Change" and "Yeah" were recorded by Yolanda Adams on Mountain High... Valley Low. At the same time, Mary Mary as a musical entity took shape. They have won multiple awards, including three Grammys. On December 23, 2010, Mary Mary along with Bebe & Cece Winans featuring the West Angeles Church of God in Christ Choir performed on The Tonight Show.
The duo was subsequently signed to Columbia Records/C2 Records and decided to perform under the name Mary Mary, honoring Mary, the mother of Jesus and Mary Magdalene. They were first gospel act to record for the industry giant Columbia Records since Tramaine Hawkins in the mid-1990s. Their first single, "Shackles (Praise You)" became a crossover hit, being popular with gospel, R&B, and pop audiences. It was a Top 5 R&B and Top 10 pop hit, and peaked at No. 28 on the Billboard Hot 100 chart. It became the first gospel song in five years to crack the R&B top ten and gained wide exposure on the MTV video cable channel. The album was a huge success because it offered a younger, hipper version of gospel that audiences could relate to. Their debut album, Thankful was released in May 2000. It peaked at No. 1 on the Gospel album chart and at No. 59 of the overall Top 200 chart, and was certified Platinum for shipments of one million copies in the USA. It went on to win the Grammy Award for Best Contemporary Soul Gospel Album. The second single "I Sings" features rapper BB Jay. Both singles were also hits in the UK and Europe, and to this day remain popular with Christian youths in the US, Latin America, and Europe. Their only Top 10 UK hit to date is "Shackles (Praise You)", which reached No. 5 in the UK Singles Chart in June 2000. The follow-up "I Sings" peaked at UK No. 32.
With their second album Incredible, the duo was able to maintain their success. Soon after its July 2002 release it was No. 1 on the Gospel chart and was able to enter the Top 20 of the Top 200 album chart. Incredible was later on certified Gold for 500,000 copies sold in the United States. The album's singles were In The Morning and I Try. While this album charted higher than their debut, sales were lower. The duo attributed the lower sales to less aggressive promotion due to label switchovers and the advent of music piracy.
Mary Mary and A Mary Mary Christmas (2005–06)
After taking time off to have children, Mary Mary released their self-titled third album, Mary Mary, in July 2005. It became the duo's first album to enter the Top 10 on Billboard and was later on certified Gold for sales of 500,000 copies. The first single "Heaven" contained a sample from seventies soul trio the Honey Cone's "Want Ads". Heaven made history and broke chart records as it had an unprecedented nine week run as the No. 1 record on Billboard's Gospel Radio chart. The second single, "The Real Party (Trevon's Birthday)" debuted at No. 43 on the Gospel Radio Chart. The third single, "Yesterday", also became a hit, especially on the Adult R&B charts where it peaked at No. 10. On the R&B/Hip Hop chart, the song became their second biggest hit since "Shackles" in 2000, reaching the No. 50. The album's final single, "Believer" indicated testimonies of being a Christian. The song hit No. 33 on the Gospel Radio chart.

The album held the No. 1 position on the Billboard Gospel Album chart for over six months since its release. Warryn Campbell again returned to produce the album and saw collaborations with Kierra Sheard, David Banner, Marvin Winans, Daryl Coley, Andrae Crouch, Rance Allen, Dorinda Clark Cole, Joe Ligon, Walter Hawkins, Tramaine Hawkins, and Karen Clark Sheard.

The duo (along with Warryn Campbell) was nominated as songwriters at the 52nd Grammy Awards in the Best Gospel Song category for "God in Me" while the Israel Houghton song they were featured on "Every Prayer" was also nominated.

Controversy and criticism
Although the Campbell sisters have been in the urban Gospel industry for years, they have been criticized for their "worldly" sound, most notably in the song "God in Me", and allegations that the song promotes "prosperity gospel".  The controversy grew when they worked with T-Pain for "God in Me". Since then, the sister duo has said in interviews that they would like to work with more secular artists.
