Mont Park Asylum was a psychiatric hospital located in Melbourne, Australia. Mont Park Hospital for the Insane was opened in April 1912. Its proclamation as a Hospital for the Insane was published in the Government Gazette on the 23 October 1912. Farming continued for many years until residential development encroached along Plenty Rd. and people began to complain in newspapers about the smells coming from the hospital grounds from the vicinity of the milking sheds and piggeries. The complex was served by the freight only Mont Park railway branch line.
