James Medbury MacKaye (April 8, 1872 - January 22, 1935) was an American engineer and philosopher.

MacKaye was born in New York City, the son of actor Steele MacKaye and Mary (Medbery) MacKaye, and brother of poet Percy MacKaye and conservationist Benton MacKaye. He attended Grammar School No. 40 near Groton, Massachusetts and Packard's Business College in New York, and in 1895 obtained an SB degree from Harvard University. In early 1890 MacKaye worked as a patent lawyer with the Census Bureau in Washington, and in April 1891 he became secretary to Nathaniel Southgate Shaler at the Harvard Geological Department, holding for a number of years various minor appointments in that institution. He joined the Boston firm Stone & Webster in 1899, where he worked as a research engineer. During the 28 years that he remained affiliated to that company he published several books on ethics, economics and politics, including Americanized Socialism, The Logic of Conduct and, most notably, The Economy of Happiness.
