Hyneria is a genus of bony fish within the extinct Osteolepiformes from the Upper Devonian of North America (approx. 360 mya ). Only a few fossil finds from the sedimentary rocks in the US state of Pennsylvania are known, which consist of parts of the skull and the shoulder girdle . Hyneria probably reached a body length of three to four meters and could have been one of the top predators in their habitat atthat time. Characteristic for the genus are a wide, blunt snout, small eyes, a well-developed system of lateral lines on the head and on the body and scales with sawn outer edges.

The name chosen by Keith Stewart Thomson in his first description in 1968 for the new genus refers to the village of Hyner , as the first fossils ( holotype ) in the Oswayo formation were found nearby . The addition of the only known species, H. lindae, honors Thomson's wife.

Hyneria is probably closely related to the approximately identical genus Eusthenodon from the Famennium . The question of whether Hyneria is identical with this genus ( younger synonym ) is still open due to the conservation status of the fossil material.

Hyneria is named after the village of Hyner, Pennsylvania , where the first fossils were found.
