Alastair Harvey MacLennan, AO, MB ChB, MD, FRCOG, FRANZCOG (born 28 March 1945) is a Scottish-Australian physician, professor of obstetrics and gynaecology, medical researcher, and a community health advocate. He studied and practised medicine in Glasgow, Chicago, and Oxford before moving to Australia in 1977 to take up a position at the University of Adelaide, where he went on to become the Professor and Head of the Discipline of Obstetrics and Gynaecology in 2006. He retired from his full-time academic position in 2013, and he is now Emeritus Professor of Medicine. He leads research projects at the Robinson Research Institute, and he is Head of the university's Cerebral Palsy Research Group.

His research has focused on foetal growth restriction, prematurity, parturition, and menopausal medicine. His current research investigates the causes of cerebral palsy, especially dispelling the myth that it is caused by oxygen deprivation or difficulties during birth.

He is a founding member of the Friends of Science in Medicine. He was appointed an Officer of the Order of Australia for his services to medicine as a practitioner, a researcher, and a teacher.
