Josephine Hart, Lady Saatchi (1 March 1942 – 2 June 2011), was an Irish writer, theatrical producer and television presenter who lived in London. Lady Saatchi wrote the novel Damage, which was the basis for the 1992 film of the same name, directed by Louis Malle and starring Jeremy Irons, Juliette Binoche and Rupert Graves.
Born at Mullingar, County Westmeath, she attended a convent school at Carrickmacross, County Monaghan, where she was encouraged by the nuns to recite verse at Irish festivals. She moved to London in 1964.
Formerly a director of Haymarket Publishing, Hart was a founder of Gallery Poets and West End Poetry Hour. She produced several West End plays, including the Evening Standard Award winner The House of Bernarda Alba by Federico García Lorca.
