Henrietta Antonia Clive, Countess of Powis (née Herbert; 3 September 1758 – 3 June 1830), was a British writer, mineral collector, and botanist.

[3] As her collection was growing, Lady Clive contacted prominent collectors and mineral dealers, such as James Sowerby, John MacCulloch and the Countess of Aylesford.

The minerals in Lady Clive's collection, numbering up to 1,000, are arranged systematically by chemistry, as was usual in the early 19th century.

[2] Upon arriving in India, Lady Powis also created a garden and kept a record of the plants in the area of Mysore and the Carnatic region.

The Countess of Powis died at Walcot Hall in 1830 aged 71 and was buried at Bromfield Parish Church, near Oakley Park.
