Janet Erskine Stuart, RSCJ, also known as Mother Janet Stuart, was a Roman Catholic nun and educator. She founded a number of schools.
She converted to Roman Catholicism at the age of 21 and in 1882, she entered the Society of the Sacred Heart at Roehampton. In August 1911, she was elected the fifth Superior General of the Society of the Sacred Heart and Mother Janet Stuart held the office for three years until her death, aged 56, from undisclosed causes..
She believed that each parent had the right to ask the teachers: "What have you done with my child, for my child? Show me the trace of your influence on her mind, heart, character, and conduct". She also believed, "it is not so much what we say or do that educates; what really educates is who we are". Sister (later Mother) Janet Stuart insisted that educators must "bring up children for the future, not for the present".
Her writings included "The Education of Catholic Girls" (1912), "The Society of the Sacred Heart" (1914), and "Highways and By-ways in the Spiritual Life". Stuart contributed also to the Catholic Encyclopedia.
