Frances Greville (née Macartney; c. 1724 – 1789) was an Anglo-Irish poet and celebrity in Georgian England.
Horace Walpole's poem The Beauties (1746) mentions her as "Fanny" among the most prominent women at court.
Frances Greville's own career as an amateur poet was marked by one resounding success: her poem, "Prayer for Indifference", first published in the Edinburgh Chronicle, in 1759, offers an attack on the cult of sensibility.
She was a known conversationalist, befriending Charles and Frances Burney, as well as Richard Brinsley Sheridan, who dedicated his The Critic to her.
Frances died 28 July 1789 at Hampton, London and is buried at St Peter's Church, Petersham.
