Mãe Stella de Oxóssi was a iyalorixá, or priestess in the Brazilian Candomblé religion. She was the fifth iyalorixá of Ilê Axé Opô Afonjá, a Candomblé terreiro in Salvador, Bahia, Brazil. Mãe Stella was trained as a public health nurse. She was initiated into the Candomblé religion in 1939 and became the iyalorixá of Ilê Axé Opô Afonjá in 1976. Mãe Stella is noted for writing on the beliefs and practices of Candomblé for the general public, rather than practitioners. She lived in the interior of Bahia after a stroke and was interred in Salvador after her death in 2018.
