Lucus Pisaurensis is a sacred grove or lucus of ancient Pisaureum, modern Pesaro in Italy. It is just outside the coastal comune of Pesaro, between the Colle della Salute and the Collina in Santa Veneranda. It is in the Pesaro e Urbino Province of Marche, a pre-Imperium Romanum region of the Sabines and Latins peoples.

Pesaro (Italian), fr. Pisaurum (latin), pis (pi π, plural) + (aurum, reflecting gold).^[1]

The eighteenth-century Italian aristocrat or patrician Annibale degli Abati Olivieri discovered the grove in 1737 in Pesaro in a farm field he owned (Il Pignocco).^[2][3] in Pesaro.^[4] He reported this in a manuscript published in 1738, Pisaurensia Marmora, ("Marble of Pesaro-Umbria").^{[5][better source needed]} Olivieri said that he found the grove in a field by the Chiostro di Santo Gaetano dei Conti. He called the site Lucus Pisaurensis (Sacred Grove of Pesaro) and gave a brief description of his findings. Olivieri wrote that he planned to publish a future work called De Luco Sacred Veterum Pisaurensium ("The Sacred Grove of Ancient Pisaurensis"), once excavations were completed. This was never published and interest in the lucus disappeared after Oliviera's death.^{[citation needed]}

The grove was rediscovered and archaeological interest in the site renewed during excavations in the 21st century.^[15][16][17] It has been suggested that the site was a meeting place for different groups of people.^[6]
