Homer Hasenpflug Dubs (March 28, 1892 – August 16, 1969) was an American sinologist and polymath. Though best known for his translation of sections of Ban Gu's Book of Han, he published on a wide range of topics in ancient Chinese history, astronomy and philosophy. Raised in China as the son of missionaries, he returned to the United States and earned a Ph.D. in philosophy (1925). He taught at University of Minnesota and Marshall College before undertaking the Han shu translation project at the behest of the American Council of Learned Societies. Subsequently, Dubs taught at Duke University, Columbia University and Hartford Seminary. In 1947, Dubs moved to England to take up the Chair of Chinese at Oxford University, which had been vacant since 1935. He retired in 1959 and remained in Oxford until his death in 1969.

Homer H. Dubs, like many early American sinologists, had his introduction to the subject as the child of missionary parents in China. Born in Deerfield, Illinois, he spent his childhood in Hunan Province. He studied briefly at Oberlin College and then graduated from Yale University (1914) with a major in philosophy. Subsequently, he earned an A.M. in philosophy at Columbia University and a B.D. at Union Theological Seminary in the City of New York. He returned to China as a missionary, studying Chinese in Nanjing before moving on to work in Hunan. Returning from China, Dubs attended the University of Chicago and earned a Ph.D. in philosophy in 1925 with a dissertation entitled "The Philosophy of Hsüntze: Ancient Confusionism [sic] as Developed in the Philosophy of Hsüntze", which was the basis for his later two-volume work on the Xunzi. After receiving his degree, Dubs taught philosophy, first at University of Minnesota (1925–27) and then at Marshall College (1927–34).
