Gisekia is a genus of flowering plants. It is the only genus in the family Gisekiaceae. The family was recognized in the APG II system (2003) and assigned to the order Caryophyllales in the clade core eudicots. This represents a change from the APG system (1998), which did not recognize this family.
The genus was named by Carl Linnaeus after Paul Dietrich Giseke (1741-1796),[citation needed] a German botanist who studied under him, and who later published his notes on Linnaeus' lectures under the title Praelectiones in Ordines Naturales Plantarum (1792).
