Antoine de Jussieu (6 July 1686 – 22 April 1758) was a French naturalist, botanist, and physician. The standard author abbreviation Ant.Juss. is used to indicate this person as the author when citing a botanical name.
Jussieu was born in Lyon. He was the son of Christophe de Jussieu (or Dejussieu), an apothecary of some repute, who published a Nouveau traité de la theriaque (1708). Antoine studied at the University of Montpellier, and travelled with his brother Bernard through Spain, Portugal, and southern France. He went to Paris in 1708. Joseph Pitton de Tournefort, whom he succeeded at the Jardin du Roi, later the Jardin des Plantes, died in that year.
