Josef Sartori (30 June 1809 – 15 September 1880) was a German pharmacist and botanist.
In 1834, he accompanied Christian Leopold von Buch on his tour of Greece.
In 1837, he sent notes on his biological observations to his professors Carl Friedrich Philipp von Martius and Joseph Gerhard Zuccarini in Munich; however, this material remained unpublished.
He also shared his observations with his friend Theodor von Heldreich and following his example, from 1844, sent samples to Pierre Edmond Boissier.
In 1837, along with Xaver Landerer and Ioannis Vouros, he published the first Greek Pharmacopoeia.
