Elspeth McLachlan FAA (born 22 July 1942), an Australian neuroscientist, is a world authority on neural pathways within the autonomic nervous system.^[1] Her work has included detailed analyses of transmission in autonomic ganglia to studies of the organisation of autonomic nervous pathways and their disorder in pathological states, particularly injuries to peripheral nerves and the spinal cord.^[2]

McLachlan was born in Bowral, New South Wales, Australia.^[2]

McLachlan was educated at the University of Sydney, from which institution she received Bachelor of Science degree in 1962, and a PhD in 1973, and a Doctor of Science degree in 1994.^[3]
