Hope Mirrlees (8 April 1887 – 1 August 1978) was a British poet, novelist, and translator. She is best known for her 1926 novel, Lud-in-the-Mist, an influential fantasy novel, and for Paris: A Poem (1920), an experimental poem published by Virginia and Leonard Woolf's Hogarth Press, which critic Julia Briggs deemed "modernism's lost masterpiece, a work of extraordinary energy and intensity, scope and ambition."

Mirrlees published three novels during her lifetime: Madeleine: One of Love’s Jansenists (1919), The Counterplot (1924), and the fantasy novel Lud-in-the-Mist (1926). She also published three volumes of poetry, including Paris: A Poem, and wrote A Fly in Amber (1962), a biography of the British antiquarian Sir Robert Bruce Cotton.
