Maude Dominica Mary Petre (4 August 1863 – 16 December 1942) was a British Roman Catholic nun, writer and critic involved in the Modernist controversy. Petre was born in Margaretting, Essex, England to an old recusant family on her father's side; her mother was a convert. She was a granddaughter of the thirteenth Baron Petre and the fourth Earl of Wicklow. She was educated privately, including for a year in Rome to study scholasticism. In 1890 she joined the Daughters of the Heart of Mary, a religious order that allowed members to live in their own homes and wear street clothing instead of habits. In 1896, she was named a local superior and was named provincial in 1900.
