The Third Republic Expeditionary Fleet was a Galactic Republic fleet organized during the New Sith Wars. Assembled in part from the remains of Admiral Herqilius Arstyn's fleet which was defeated at the Battle of Gizer, the Third Fleet was under the command of Jedi Master Gavhys Narfulk. The Third Fleet was charged with opposing Darth Saleej and, later, Darth Hokhtan for control of the Perlemian Trade Route.
Several Jedi, including Raven Kaivalt and Dogr Quam, were assigned to the fleet.
