Karl Ferdinand Herzfeld (February 24, 1892 – June 3, 1978) was an Austrian–American physicist and chemist. He worked on condensed matter physics, fluid dynamics, reaction rate theory, and statistical mechanics. In seminal 1919 and 1921 papers, he derived the rate equation for unimolecular reactions and proposed the Lindemann mechanism of third-body deactivation in unimolecular reactions. In 1927, he was the first to quantify when a substance is a metal or an insulator. The Goldhammer–Herzfeld criterion to classify metalloids is named after him. Herzfeld and Frank O. Rice developed the theory of translational-vibrational energy transfer, and proposed the radical mechanism for pyrolysis in 1934, known as the Rice–Herzfeld mechanism. Herzfeld also wrote on philosophy and theology. He was married to anthropologist Regina Flannery.
