Erich von Kahler (October 14, 1885 – June 28, 1970) was a mid-twentieth-century European-American literary scholar, essayist, and teacher known for works such as The Tower and the Abyss: An Inquiry into the Transformation of Man (1957).

In 1933, deprived of his German citizenship by the Nazi regime, he left Germany, emigrating to the United States in 1938 after a period of residence in England.

He was a friend of Albert Einstein, Thomas Mann, and Hermann Broch, who wrote Tod des Vergils at Kahler's home, One Evelyn Place in Princeton.

Hanna Loewy Kahler exchanged letters with theoretical physicist David Bohm, with whom she was for some time engaged to be married,[5] after he left the USA for Brazil and these, as well as other letters in her possession, have contributed to an understanding of historic events surrounding the Solvay Conference of 1927 and Bohm's exile in Brazil.
