The Giant oarfish, (Regalecus glesne), also called the king of herrings, is a species of oarfish of the family Regalecidae. It is an oceanodromous species that has a worldwide distribution, excluding polar regions.

The Giant oarfish is the world's longest known bony fish. Its shape is ribbonlike, narrow laterally, with a dorsal fin along its entire length, stubby pectoral fins and long, oar-shaped pelvic fins, from which its common name may be derived. Its coloration is silvery with dark markings, and its fins are red.

Its physical characteristics and its undulating mode of swimming have led to speculation that it may be the source of many "sea-serpent" sightings.
