Sister Mary Thomasita Fessler O.S.F. was an American painter and religious sister. Her work consisted of paintings, sculptures and designs for stained-glass windows. She used the signature SMT, Sr. T or Sr. Thomasita.

Sr. Thomasita was born as Majella Nicola Fessler, in Milwaukee, Wisconsin, the granddaughter of the prominent architect Erhard Brielmaier. She joined the Sisters of St. Francis when she was seventeen years of age and went on to graduate from University of Wisconsin-Milwaukee, and the School of the Art Institute of Chicago.

One of the most publicly known artists within the Brielmaier artist family, she was profiled by Life magazine in a 1953 feature story written by Jaqueline Mitchard. Prior to the publication, Sr. Thomasita was being asked by the Church to reconsider whether she should remain in the convent due to what the church hierarchy was 'seeing' in her artwork.
