Jean Kickx (17 January 1803, Brussels – 1864) was a Belgian botanist. His father, also known as Jean Kickx (1775–1831) was a botanist and mineralogist; his son Jean Jacques Kickx (1842–1887) was a professor of botany at the University of Ghent.
In 1830 he obtained his PhD at Leuven, later serving as a professor of botany in Brussels (1831–1835) and at the University of Ghent (1835–1864). He was a co-founder of the Société royale de botanique de Belgique.[1]
The mycological genus Kickxella (order Kickxellales) was named in his honor by Eugène Coumans.[1]
