A **cyberneticist** or a **cybernetician** is a person who practices cybernetics.

Heinz von Foerster once told Stuart Umpleby that Norbert Wiener preferred the term "cybernetician" rather than "cyberneticist", perhaps because Wiener was a mathematician rather than a physicist.

The word "cyberneticist" was used by Nicolas Rashevsky who began as a theoretical physicist. Robert Rosen, who began his career as a mathematician, regarded neurocybernetics—and more generally biocybernetics—as fields closely allied to mathematical biology and mathematical biophysics in which control theory and dynamical system theories also play significant roles.

Today "cybernetician" is preferred by members of the American Society for Cybernetics.^{[1]}
