André Chapelon (26 October 1892 – 22 July 1978) was a noted French mechanical engineer and designer of advanced steam locomotives. Engineer of Ecole Centrale Paris, he was one of very few locomotive designers who brought a rigorous scientific method to their design. Efficiency was one of Chapelon's primary concerns in design; some of his locomotives exceeded 12% efficiency, which for a steam locomotive was exceptional.
