François van Rysselberghe (24 August 1846 – 3 February 1893) was a Belgian scientist who was the forerunner or the inventor of numerous devices in the fields of meteorology and telephony. He invented, in particular, a system allowing several telephone signals to pass through telegraph cables. The generalization of the Van Rysselberghe System (French: Système Van Rysselberghe) in Belgium in 1884, and then abroad, promoted the development of this new mode of communication, making it a pioneer of long-distance telephone communications.
