The Farnese Gardens (Orti Farnesiani sul Palatino or "Gardens of Farnese upon the Palatine") are a garden in Rome, central Italy, created in 1550 on the northern portion of Palatine Hill, by Cardinal Alessandro Farnese. They were the first private botanical gardens in Europe; the first botanical gardens of any kind in Europe were started by Italian universities in the mid-16th century, only a short time before.
Alessandro Farnese was appointed Cardinal Deacon of the Roman Catholic Church in 1534 at the age of 14, by Paul III, his grandfather, who had been elected to the papacy two months previously. He is remembered for being an antiquarian who assembled the greatest collection of Roman sculpture assembled in private hands since antiquity. In 1550, when Farnese acquired a northern portion of Palatine hill (historically the oldest of Rome's seven hills) he had ruins from a Roman palace of Tiberius at the northwest end of the hill top filled in, and converted to a summer home. The site overlooks the Roman Forum and is near the Arch of Titus. He called this Horti Farnesiani 
The garden was divided into the classic style of quadrants with a well or a fountain at its centre, deriving from the design of the Roman peristilium palaces of the area, as re-created by the noted architect Vignola. The villa's design was first attributed to Michelangelo but later to Vignola and Rainaldi. The gardens were arranged in terraces. Steps from terrace to terrace ran past the Ninfeo della Piogga (a nymphaeum) to end in the Teatro del Fontanone. Aviaries were situated in the center Casina, which boasted frescoes. Walking paths at the base of the Domus Tiberiana included underground passages and ancient sculptures.
- Now mostly in Naples, after passing by inheritance to the Bourbon-Parma kings; it ranked with the papal collections in the Cortile del Belvedere, and the city's own collection housed at the Campidoglio.
