Millard Henry Alexander (born February 17, 1943, Boston, Massachusetts) is a Distinguished University Professor at the University of Maryland, with appointments in the Department of Chemistry and Biochemistry and the Institute for Physical Science and Technology. He is the author of over 300 publications and an active researcher in the fields of molecular collision dynamics and theoretical chemistry.

Alexander's research focus is the quantum-mechanical aspects of molecular collisions, in particular those involving open-shell species. More specifically, Alexander's work has focused on understanding chemical reactions where the Born-Oppenheimer approximation can be violated, by means of nonadiabatic coupling, spin-orbit interactions and conical intersections. Alexander's work is particularly important in understanding the F+H2→FH+H and Cl+H2→HCl+H reactions.

Alexander is a fellow of the American Physical Society and of the American Association for the Advancement of Science, and a member of the International Academy of Quantum Molecular Science. In 2015 he received the Herschbach Medal for contributions to the theoretical study of the dynamics of molecular collisions.

Since 2012 Alexander has served as the President of the Telluride Science Research Center.
