William Humphrey Beik (1941–2017) was an American professor of French history, specialising in early modern France.
Beik's father, Paul Beik, was a professor of history at Swarthmore College who carried out research on the French Revolution, so that William was partially educated in France. William took degrees from Haverford College (B.A. 1963) and Harvard University (M.A. 1966; Ph.D. 1969). From 1968 to 1990 he taught at Northern Illinois University, and in 1990 became Professor of French History at Emory University, retiring in 2007. His Absolutism and Society in Seventeenth-Century France (1985) received the American Historical Association's Herbert Baxter Adams Prize. He died in Pittsburgh on 31 August 2017.
