The Nicholson Museum was an archaeological museum at the University of Sydney home to the Nicholson Collection, the largest collection of antiquities in both Australia and the Southern Hemisphere. Founded in 1860, the collection spans the ancient world with primary collection areas including ancient Egypt, Greece, Italy, Cyprus, and the Near East. The museum closed permanently in February 2020, and the Nicholson Collection is now housed in the Chau Chak Wing Museum at the University of Sydney, open from November 2020. The museum was located in the main quadrangle of the University.
