Ferenc A. Váli (May 25, 1905 - November 19, 1984) was a Hungarian lawyer, writer, and political analyst specializing in international law.
During World War II the Hungarian government sent him to Istanbul, Turkey, on a confidential mission to make contact with the Allied powers.
Returning to Hungary after the war, he was international law adviser to the Hungarian Ministry of Finance, and continued teaching at the University of Budapest until he was banned from the faculty and from the ministry by the Communists early in 1949.
With a fellowship from the Rockefeller Foundation, he did research in London, Paris and The Hague, and after December 1957, in New York and Washington.
In September 1961 he joined the government department at the University of Massachusetts Amherst and stayed there until his retirement in 1975.
