Carl Friedrich von Ledebour (8 July 1786, Stralsund – 4 July 1851, Munich; also Karl Friedrich von Ledebour) was a German-Estonian botanist. Between 1811 and 1836, he was professor of science in the University of Tartu, Estonia. His most important works were Flora Altaica, the first Flora of the Altay Mountains, published in 1833, and Flora Rossica, published in four volumes between 1841–1853, the first complete flora of the Russian Empire. The plant genera Ledebouria (in the Asparagus family, Asparagaceae), and Ledebouriella (from the family Apiaceae) are named in his honor.
