Alan Mackay-Sim AM (16 May 1951 – 4 January 2023) was an Australian biomedical scientist specialising in adult stem cell research, and winner of the 2017 Australian of the Year. Some of his research focused on olfactory ensheathing cells, which are cells in the human nose that interact with the nervous system to cause a sense of smell.

His research into stem cells contributed to the treatment of spinal cord injuries. The restoration of mobility to Darek Fidyka, a Polish paraplegic man, used research by Mackay-Sim.

He began his studies at Macquarie University, where he received a Bachelor of Arts in 1973, an Honours degree in 1974, and a PhD in 1980. His doctoral thesis was titled "Olfaction and stress in mice."

After completing his studies, Mackay-Sim conducted research and taught at the University of Pennsylvania and the University of Wyoming in the United States. In 1987, he returned to Australia and joined Griffith University, where he focused his research on the olfactory system and adult stem cells.

He served as the founding Director of the National Centre for Adult Stem Cell Research and as Deputy Director of the Eskitis Institute for Cell and Molecular Therapies..
