Hyperoglyphe antarctica, the Antarctic butterfish, bluenose warehou, deepsea trevally, blue eye trevalla, blue-eye cod, bluenose sea bass, or deep sea trevalla, is a medusafish of the family Centrolophidae found in all the southern oceans, at depths of between 40 and 1,500 m. Its length is up to about 140 cm, with a maximum published weight of 60 kg.

This species is present in five distinct areas: Argentina, South Africa, southern Australia, Saint-Paul & Amsterdam French Austral Islands and New Zealand.

Spawning appears to occur in an area north east of Tasmania during March and April.

Recently Antarctic butterfish of approximately 10 cm have been found living in association with large masses of floating kelp.

These young fish form schools over hard bottom at depths of around 350–450 m, moving to deeper waters as they grow.
