Sarah Green (fl. 1790 - 1825) was an Irish-English novelist and writer.

Green was apparently born in Ireland, though moved to London. She may have authored Charles Henly, or, The Fugitive Restored (1790), but the first fictional work which can definitely be attributed to her is Court Intrigue, or, The Victim of Constancy (1799). A further sixteen novels followed, the last being Parents and Wives, or, Inconsistency and Mistakes (1825).
