"Shackles (Praise You)" is the debut single by American gospel singer-songwriter duo Mary Mary, released on March 7, 2000, in the United States. It is considered the group's signature song. Stan North of GospelFlava.com deemed it one of the pioneer songs of urban gospel music. The song was originally recorded and released in December 1999 upon Mary Mary's signing with Columbia Records and was re-released one month later as a promotional single for their upcoming debut album, "Thankful". They both feature the same track listing but different album covers, the second using a picture of the duo.
