"Mary, Did You Know?" is a Christmas song addressing Mary, mother of Jesus, with lyrics written by Mark Lowry in 1984, and music written by Buddy Greene in 1991. It was originally recorded by Christian recording artist Michael English on his self-titled debut solo album in 1991. At the time, English and Lowry were members of the Gaither Vocal Band, and Greene was touring with them. The song reached Number 6 on CCM Magazine's Adult Contemporary Chart. Lowry would record the song several times himself, most notably with the Gaither Vocal Band on their 1998 Christmas album, Still the Greatest Story Ever Told.
The song has since gone on to become a modern Christmas classic, recorded by hundreds of artists over the years, across multiple genres. Different versions have reached the top ten in the Billboard R&B and Holiday charts..
