Hans Marchand (1 October 1907 – 13 December 1978) was a German linguist. He studied Romance languages, English and Latin, and after fleeing Germany during the Third Reich was a lecturer of linguistics at Istanbul, Yale University, and Bard College. From 1957 to 1973 he was a professor at the University of Tübingen.
Marchand published works on linguistic phenomena occurring in languages such as English, French, Turkish and Italian, but became famous in his discipline for his theories on word-formation in the English language. Linguists following his approach are called Marchandeans.
