Wynona Carr (August 23, 1923 – May 11, 1976) was an American gospel, R&B and rock and roll singer-songwriter, who recorded as Sister Wynona Carr when performing gospel material.

Wynona Merceris Carr was born in Cleveland, Ohio, where she started out as a gospel singer, forming her own five-piece group The Carr Singers around 1945 and touring the Cleveland/Detroit area. Being tipped by the Pilgrim Travelers, who shared a bill with Carr in the late 1940s, Art Rupesigned her to his Specialty label, giving Carr her new stage name “Sister” Wynona Carr (modelled after pioneering gospel singer Sister Rosetta Tharpe) and cutting some twenty sides with her from 1949 to 1954, including a couple of duets with Specialty’s biggest gospel star at the time, Brother Joe May.
