The Redpath Museum is a museum of natural history belonging to McGill University located at 859 Sherbrooke Street West ( 45°30′16.20″N, 73°34′38.60″W) in Montreal, Quebec, Canada. It was built in 1882 as a gift from the sugar baron Peter Redpath. It is rumoured that it was part of an effort to ensure that Sir William Dawson would not leave the university. It houses collections of interest to ethnology, biology, paleontology, and mineralogy/geology. The collections were started by some of the same individuals who founded the Smithsonian and Royal Ontario Museum collections. The current director is David Green.
It is the oldest building built specifically to be a museum in North America. Although small, its striking architecture is an important example of neo-classical design. It has figured as a set, both inside and out, for movies and commercials. (See Barnum (1986) starring Burt Lancaster, Eye of the Beholder, (1999) starring Ashley Judd).

Geology (mineralogy) collection
The museum's important collection of fossils owes much of its beginning to Sir William Dawson who provided not only many of the fossils of plants from his native Nova Scotia, but procured many important specimens from around the world. Dr. Thomas Clark, for many years up until his death, was a fixture at the museum and was renowned for his pioneering work on fossils from the Burgess Shale, some of the oldest known anywhere.
