Admiral Raner was a 24th century Starfleet flag officer. She served as the head of Starfleet Security in 2370.

Raner was responsible for ordering Admiral Erik Pressman to recover the USS Pegasus and further experimentation on the prototype for a Federation phasing cloaking device which was lost in 2358. Due to the sensitive political nature of the experiment, she ordered Pressman to keep the effort a secret, and gave written orders to Commander William T. Riker to assist him without informing his captain, Jean-Luc Picard.

Raner was presumably prosecuted along with Pressman for violating the Treaty of Algeron when the cloaking device was brought to light by Riker. (TNG: "The Pegasus")
