Maynea is a monospecific genus of marine ray-finned fish belonging to the family Zoarcidae, the eelpouts.

Maynea was first proposed as a monospecific genus in 1871 by the Scottish naturalist Robert Oliver Cunningham when he described Maynea patagonica, the type locality of this species being the Otter Islands, Smyth Channel in the Magellan Straits in southern Chile.

[1] In 1988 M. Eric Anderson confirmed that Maynea was a monospecific genus and that Cunningham's M. patagonica was a junior synonym of Conger puncta which had been described in 1842 by Leonard Jenyns from type specimens collected on the second voyage of HMS Beagle in the Beagle Channel in Tierra del Fuego.

[4] Maynea, the genus name, honours Captain Richard Charles Mayne, commander of HMS Nassau on the survey expedition to the Straits of Magellan, 1866–9 on which holotype of M. patagonica was collected.

[2] Maynea is endemic to the Magellan Province in the southeastern Pacific and southwestern Atlantic Oceans where it occurs in the inlets of southern Chile, around Tierra del Fuego and the Falkland Islands.
