Walter Franz (8 April 1911, in Munich – 16 February 1992, in Münster) was a German theoretical physicist who independently discovered the Franz–Keldysh effect.
Franz was a student of Arnold Sommerfeld at the Ludwig-Maximilians-Universität (LMU) in Munich, Germany. There he was granted the doctoral degree Dr.phil. in 1934. The (German) title of his dissertation was Comptoneffekt am gebundenen Elektron. In the preface to the book Optik, Sommerfeld cited him for "the most recent and particularly lucid treatment" of the vectorial generalization of Huygens’ principle.
With Adolf Kratzer, another student of Sommerfeld, Franz co-authored the book Transzendente Funktionen. The article in which Franz independently published the Franz–Keldysh effect was published in 1958.
