August Friedrich Schweigger (8 September 1783 – 28 June 1821) was a German naturalist born in Erlangen. He was the younger brother of scientist Johann Salomo Christoph Schweigger (1779-1857).
He studied medicine, zoology and botany at Erlangen, and following graduation spent time in Berlin (from 1804) and Paris (from 1806). In 1809 he was appointed professor of botany and medicine at the University of Königsberg. In 1815, he was elected a corresponding member of the Royal Swedish Academy of Sciences. On a research trip to Sicily, he was murdered near Agrigento on 28 June 1821.
The plant genus Schweiggeria from the family Violaceae is named in his honor.
In the scientific field of herpetology, he is best known for his 1812 monograph of turtles, in which he described several new species which are still valid.
