Margaret Pole was a 16th-century English peeress and a member of the House of Plantagenet. As the daughter of George, Duke of Clarence, she held the title of Countess of Salisbury in her own right. Despite her royal lineage, she lived through the transition from the Yorkist to the Tudor dynasty. Following the death of her husband, Richard Pole, she served as a lady-in-waiting to Catherine of Aragon. Her life ended in 1541 when she was executed at the Tower of London by order of King Henry VIII.
