The Romulan bird-of-prey was a type of Romulan Star Empire starship, a bird-of-prey in Imperial Fleet service in the 22nd century. These vessels were most notably in service as combatant vessels during the Earth-Romulan War. Unlike the more streamlined type of 22nd century bird-of-prey also in use during this period, this type of bird-of-prey was cylindrical in shape, and had two cigar-shaped warp nacelles attached aft of amidships on either side of the hull.
