Mary Boulding (3 May 1929 – 11 November 2009) was an English nun, writer and translator. The oldest of three daughters, she declined a scholarship to Lady Margaret Hall, Oxford, and went to Stanbrook Abbey to become a nun. Boulding took her solemn vows in April 1952 after expressing her wish to delay her profession of vows, but this was remedied by the abbess Elizabeth Sumner who challenged her to theological endeavors. Her first book was published in 1973, and she joined the theological commission of the English Benedictine Congregation in the late 1970s. Boulding later undertook a six-month tour of the Holy Land, Australia, and Japan in preparation for the marking the fifteenth centenary of Benedict of Nursia's birth in 1980, where she addressed mixed audiences. She spent the years 1985 to 2004 living as a hermit before returning to Stanbrook in early 2004 and spending the final years of her life translating, revising, and travelling.
