Elizabeth Catherine Hunter, Lady Clarke (c. 1740 – 1795), best known as Kitty Hunter, was an English noblewoman. She was the daughter of Thomas Orby Hunter, a member of parliament and lord of the Admiralty. In 1762, she eloped to mainland Europe with Henry Herbert, 10th Earl of Pembroke, causing a scandal. A year later the couple returned to England and Pembroke reconciled with his wife. Hunter had a son by Pembroke, Augustus Retnuh Reebkomp, who was supported by the Pembroke family and became a naval officer. Hunter was the mistress of Augustus Hervey before marrying army officer Alured Clarke. When Clarke was knighted she became known as Lady Clarke.
