Henrietta Antonia Clive, Countess of Powis (1758–1830), was a British mineral collector and botanist. She married Lord Clive’s eldest son and heir, Edward Clive, in 1784. The marriage was beneficial to both families; the bride’s family had a prestigious name but considerable debts, while the groom’s had accrued wealth from during Clive’s military campaigns in India. The couple finally settled in Walcot Hall, Shropshire.
