Stanley Lewis Engerman (born March 14, 1936) is an economist and economic historian at the University of Rochester. He received his Ph.D. in economics in 1962 from Johns Hopkins University. Engerman is known for his quantitative historical work along with Nobel Prize–winning economist Robert Fogel. His first major book, co-authored with Robert Fogel in 1974, was Time on the Cross: The Economics of American Negro Slavery. This significant work, winner of the Bancroft Prize in American history, challenged readers to think critically about the economics of slavery. Engerman has also published over 100 articles and has authored, co-authored or edited 16 book-length studies. Engerman served as president of the Social Science History Association as well as president of the Economic History Association. He is professor of Economics and Professor of History at the University of Rochester, where he teaches classes in economic history and the economics of sports and entertainment. From 2009 to 2012 he was a visiting professor in the Harvard University Economics Department, where he taught the economics of sports and entertainment. Professor Engerman has taught many influential individuals, including Evelyn Brooks Higginbotham, David Eltis, Gary Gorton, Evelyn Jennings, Art Laffer, Frank Lewis, Jeremy Lin and Robert L. Paquette. The former National Economic Council executive for the Trump administration, Larry Kudlow has described Dr. Engerman as the most impactful educator in his studies (although Dr. Engerman professes to have no recollection of ever teaching Mr. Kudlow).

Reminiscent of Charles A. Beard's economic analysis of the Constitution in its longevity, Time on the Cross made a variety of politically-charged claims based on cliometric quantitative methods. Fogel and Engerman claimed that slavery remained an economically viable institution and slave ownership was generally a profitable investment, slave agriculture was very efficient, and the material conditions of the lives of slaves "compared favorably with those of free industrial workers." Charles Crowe offered a summary of the work: "The cliometricians announced the scientific discovery of a vastly different South led by confident and effective slaveowning entrepreneurs firmly wedded to handsome profits from a booming economy with high per capita incomes and an efficiency ratio 35 per- cent greater than that of free Northern agriculture. In the new dispensation the efficient,
