Lady Louisa Augusta Greville (14 April 1743[1] – buried 11 August 1779)[2] was an English engraver.

She became a remarkably proficient and talented engraver, a medium which was increasingly popular amongst women during the eighteenth century.

[3] Other members of Louisa's family also practised in watercolours, pencil, pen and engraving, including her brothers and sisters.

Most of her surviving artworks are engravings after examples by Annibale Carracci, Salvator Rosa, Marco Ricci, Guercino among others.

[1][4] She also produced prints of her father's home Warwick Castle, several examples of which survive in the Richard Bull Album kept at The British Museum.
