Gilbert C. Gerard (January 23, 1943 – December 16, 2025) was an American actor, known for his role as Captain William "Buck" Rogers in the 1979–81 television series Buck Rogers in the 25th Century.

Gerard was employed as an industrial chemist, and within a few years he became regional manager of the chemical company headed by governor Winthrop Rockefeller. Gerard's employers said they would appoint him as vice president if he undertook a master's degree, so he resigned rather than explain that he did not have a bachelor's degree.
