For the tribal title of the same name, please see Chief (tribal).

Chief (or jefe in the Spanish language) was a common designation for leading officers and enlisted personnel aboard Federation starships and installations.

When used as a title referring to an officer it denoted a member of positional authority, such as a staff officer, or department head status.

In reference to an enlisted person, it referred directly to rank. (TOS: "Mirror, Mirror")


The role of "Chief Judge" was referenced in the final draft script of TOS: "Court Martial". However, as that episode continued to develop, the title was changed to "President of the Court".
Furthermore the script of Star Trek mentioned the function of station chief.
