Robert R. Warnecke was a noted French electrical engineer.

Warnecke was director of research at the Compagnie générale de la télégraphie sans fil (CSF) in Paris. He received the 1954 IEEE Morris N. Liebmann Memorial Award "for his many valuable contributions and scientific advancements in the field of electron tubes, and in particular, the magnetron class of traveling wave tubes."
