Philipp Eduard Anton von Lenard (German: [ˈfɪlɪp ˈleːnaʁt] ; 7 June 1862 – 20 May 1947) was a German experimental physicist who received the Nobel Prize in Physics in 1905 for his work on cathode rays.

As an active proponent of the Nazi ideology, Lenard supported Adolf Hitler in the 1920s and was an important role model for the Deutsche Physik movement during the Nazi period. He labeled Albert Einstein's contributions to theoretical physics as "Jewish physics".
