chief petty officer (CPO) is a type of rank, specifically, an enlisted rate in naval services and space forces, most notably the Starfleet of the United Federation of Planets.

A chief petty officer is an advancement of petty officer, and is an NCO rate, a grade higher than an petty officer first class and a grade below senior chief petty officer in some rank structures. This grade is roughly equivalent with the authority of a level of sergeant of military forces.

Chief petty officer uniform insignia existed in Starfleet, a rank insignia worn on the Starfleet uniforms of numerous eras. (FASA RPG modules: Cadet's Orientation Sourcebook, Star Trek: The Next Generation Officer's Manual)
