Marie-Anne-Marcelle Mallet (March 26, 1805 – April 9, 1871) was a Roman Catholic nun and founder of the Sisters of Charity of Quebec.

[1] Marie was born to Vital Mallet and Marguerite Sarrazin in Montreal, Lower Canada.

Her father died when she was five and she spent the rest of her childhood living with an aunt and uncle in Lachine and in boarding with the Congregation of Notre Dame.

Mallet joined the Sisters of Charity of the Hôpital Général of Montreal as a novice in 1824 and became a nun in 1826.

Mallet was not re-elected as mother superior in an election held in 1866 and returned to live life as a simple nun.
