Jean Audrey Knight (née Caliste; January 26, 1943 – November 22, 2023) was an American R&B and soul singer from New Orleans, Louisiana.

Launching her professional career in the mid-1960s, Knight was best known for her 1971 hit single "Mr. Big Stuff", released by Stax Records.

[2][3][4][5][6] After graduating from high school, she began singing at Laura's Place, her cousin's bar, and caught the attention of many different bands who were willing to accompany her.

By the late 1960s, it was obvious that Knight's career was not living up to her high expectations, so she went to work as a baker in the cafeteria of St. Mary's Dominican College in New Orleans.

[6] It went double-platinum and received a Grammy nomination for Best R&B Vocal Performance, Female; it lost to Aretha Franklin's version of "Bridge Over Troubled Water".

[citation needed] After leaving Stax, Knight recorded songs for various small labels, but was not able to gain any more recognition,[6] and ended up performing and touring the local oldie circuit.

Things changed in 1981, when Knight met local producer Isaac Bolden, who signed her to his Soulin' label.

[11] Although Knight waited twelve years to come out with another recording, she continued touring and performing engagements all over the world, particularly in the Southern states.

In 2003, Knight performed her biggest hit, "Mr. Big Stuff"[citation needed], on the PBS special Soul Comes Home.
