The Imperial Navy, also known as the Imperial Starfleet, Imperial Fleet, Imperial Battlefleet, or Imperial Space Service, is the naval branch of the Imperial Military (Fel Empire) of the Fel Empire. At its peak, it fields millions of warships, logistic vessels and fighters, maintaining Imperial control throughtout the Kristoffer's Universe.

The Imperial Navy was formed from the orginal Imperial Navy of the Galactic Empire between 44 ABY and 127 ABY, as part of Jagged Fel's Imperialization campaign during the rise of the Fel Empire under the Yuuzhan Vong War. A reorganized command structure, eventually consisting of twelve Grand Admirals, oversaw the rapid expansion of the fleet that had begun during the Yuuzhan Vong War.
