Emma Augusta Thomsen (7 August 1820 — 6 November 1897) was a Danish flower painter.
She was introduced to flower painting by Johan Laurentz Jensen (1800–1856) but was self-taught in developing the art of painting flowers in their natural surroundings.
In 1846 she sold Roser og Ipomæa and in 1855 En Blomsterkrans, ophængt paa Bøgegrene.
In 1861, she was awarded the Neuhausen Prize for the En Kurv med Blomster i det frie.
[3] She died in Copenhagen and was buried at Holmen Cemetery.
