Jan Frederik Gronovius (also seen as Johann Frederik and Johannes Fredericus) (1690-1762) was a Dutch botanist notable as a patron of Linnaeus.

John Clayton, a plant collector in Virginia sent him many specimens in the 1730s, as well as a manuscript description. Without Clayton's knowledge, Gronovius used the material in his Flora Virginica (1739-1743, 2nd ed. 1762).

In 1737 Gronovius described the Transvaal daisy, naming it Gerbera.

His son was also a botanist.
