Admiral Fitzgerald was a 23rd century Starfleet flag officer, who, in 2268, ordered USS Enterprise first officer, Spock, not to beam down to the surface of the planet Gideon in search of the missing Captain James T. Kirk. He noted that despite sympathizing deeply with the situation, Starfleet simply could not override Federation directives in such a matter. Doing so would only provoke war. (TOS: "The Mark of Gideon")
- Fitzgerald was played by actor Richard Derr.
