Argyripnus brocki, commonly known as Brock's bristle-mouth fish, is a species of ray-finned fish in the genus Argyripnus found in the Pacific Ocean.

[1] The fish is named in honor of Vernon E. Brock (1912–1971), an ichthyologist/herpetologist, for his contributions to marine biology and his support of Struhsaker's studies of the Hawaiian bathyal fishes.

[2] The fish is typically 60 mm - 70 mm, with females being longer than males.

They appear mostly translucent, with a small black patch sometimes being visible near the head.
