Karen Clark-Sheard (born Karen Valencia Clark on November 15, 1960) is an American gospel singer, musician, and songwriter. The youngest daughter of pioneering gospel choral director Mattie Moss Clark, Sheard began her career as a member of the The Clark Sisters. She is the mother of contemporary gospel singer and actress Kierra "Kiki" Sheard.

During the hiatus of the Clark Sisters, Sheard recorded her critically acclaimed and much anticipated solo album Finally Karen, which spawned her hit, "Balm in Gilead" (a re-recording of a song she originally recorded as part of The Clark Sisters back in the 1980s for their Heart & Soul album) the R&B-flavored "Just For Me" and "Nothing Without You" - a contemporary duet with R&B diva Faith Evans. Finally Karen became one of the most successful gospel albums of 1998 earning Sheard a Grammy nomination and earning her a Soul Train Lady of Soul Award for "Best Female Vocalist".

After her debut album success and much touring, Sheard was hospitalized in 2001 after one of her blood vessels burst during a minor surgery, resulting in doctors giving her a 2% chance of survival. Her testimony inspired the title name for her long-awaited sophomore project, Second Chance released in 2002, featuring a "Secret Place" - which is now considered a classic amongst fans. Sheard recorded two more live albums, including The Heavens Are Telling and It's Not Over (which featured some studio recordings), before releasing All in One, Sheard's first all-studio-recorded album in 13 years. The album debuted at #3 on the U.S. Billboard Gospel Chart and #98 on Billboard's Top 200 albums chart, while its first single "Prayed Up" has so far peaked at #10 on the U.S. Billboard Gospel Songs chart.

The "Queen of Soul", Aretha Franklin, chose Sheard to play her in her upcoming biopic, believing that only Sheard herself could play the role better than any other artist in her time.
