Joseph "Krystel" Franz Freiherr von Jacquin or Baron Joseph von Jacquin (7 February 1766 in Schemnitz (now Banská Štiavnica) – 26 October 1839 in Vienna) was an Austrian scientist who studied medicine, chemistry, zoology and botany.

The son of Nikolaus von Jacquin, he graduated from the University of Vienna as a doctor of medicine in 1788.

Between 1788 and 1791 Jacquin was sent on a scientific journey to Germany, France and England by Emperor Francis II.

He inherited his father's position as professor of botany and chemistry at the University of Vienna, which he held from 1797 until his retirement in 1838. In 1821, he was elected a foreign member of the Royal Swedish Academy of Sciences.


Regarding personal names: Freiherr is a former title (translated as Baron). In Germany since 1919, it forms part of family names. The feminine forms are Freifrau and Freiin.
