Arabella Elizabeth Roupell (23 March 1817 Newport, Shropshire – 31 July 1914 Swallowfield, Berkshire) was an English flower painter, noted for an anonymous set of flower paintings published in 1849 under the title 'Specimens of the flora of South Africa by a Lady.' Roupell was the daughter of Rev. John Dryden Piggott, rector and squire of Edgmond, and married Thomas Boone Roupell, an East India Company official, on 16 September 1840. In 1843, shortly after the birth of her eldest son, her husband was posted to the Cape for a period of service leave and she chose to accompany him.
