Patrick Gerard Quilty (20 March 1939 – 26 August 2018) was an Australian paleontologist who specialised in the surface and subsurface earth sciences of Antarctica.
The Quilty Nunataks are named for his initial service in Antarctica, at which time he was connected to the University of Wisconsin in the USA.
He later continued his Antarctic service with the University of Tasmania, rising to the position of Chief Scientist with the Australian Antarctic Division (AAD) of the Australian Department of the Environment.
