Elizabeth Caroline Mary Stuart-Wortley, Baroness Wharncliffe (née Crichton; 1779–1856), styled Lady Elizabeth Crichton from 1789 until her marriage, was an Irish-born British aristocrat and female artist known for her landscape and figurative drawing and painting. A number of these artworks are in Tate Collection and Archive.
