Sarah Siddons (née Kemble; 5 July 1755 – 8 June 1831) was a Welsh actress, the best-known tragedienne of the 18th century. Contemporaneous critic William Hazlitt dubbed Siddons as "tragedy personified".
She was the elder sister of John Philip Kemble, Charles Kemble, Stephen Kemble, Ann Hatton, and Elizabeth Whitlock, and the aunt of Fanny Kemble. She was most famous for her portrayal of the Shakespearean character Lady Macbeth, a character she made her own.
