Alfred Werner (March 31 1911–July 14 1979) (born Alfred Siegfried Weintraub) was a prominent Austro-American art critic, historian, and author who specialized in 19th and 20th-century European and American art, particularly modern art and Jewish artists.

After surviving the Dachau concentration camp, he moved to New York and authored numerous monographs on painters like Chagall, Modigliani, and Soutine.

Werner also wrote for Arts magazine, The New York Times, and Commentary, providing critical analysis of exhibitions and artists.
