Marc Lewis (born 1951) is a Canadian clinical psychologist, neuroscientist, academic, and author from Toronto, Ontario.

He was a professor at the University of Toronto from 1989 to 2010 and Radboud University Nijmegen in Nijmegen, the Netherlands from 2010 to 2016. He is particularly focused on the study of addiction. His work is informed by his own experience of drug addiction, and is notable for its focus on neuroscience and the changes addiction causes in the brain. His books include Memoirs of an Addicted Brain and The Biology of Desire, which Damian Thompson of The Spectator called "the most important study of addiction to be published for many years." He has argued that the standard view of addiction as a disease is misleading and even potentially harmful, suggesting instead that it is best viewed as a process of "deep learning." This has been controversial.

He has also written or co-written more than 75 journal articles and chapters on developmental psychology, neuroscience, addiction and related topics.
