Augusta Theodosia Drane (29 December 1823 – 29 April 1894) was an English writer and Roman Catholic nun. Born at Bromley, near Bow and brought up in the Anglican creed, she was influenced by Tractarian teachings and joined the Roman Catholic Church around 1850. She wrote, and published anonymously, an essay questioning the morality of Tractarianism, which was attributed to John Henry Newman. In 1852, after a prolonged stay in Rome, she joined the third order of St. Dominic, to which she belonged for over forty years. She was prioress of Stone, Staffordshire, where she died, aged 70.
