The sharpbeak terapon (Rhynchopelates oxyrhynchus) is a species of ray-finned fish, a grunter from the family Terapontidae.

It is found in the coastal waters of Asia from southern Japan to the Philippines.

It has a small, slightly oblique mouth which does not reach as far back as the eye.

[1] The sharpbeak terapon was first formally described as Therapon oxyrhynchus in 1842 by Coenraad Jacob Temminck & Hermann Schlegel with the type locality given as the basy of southern Japan.

[3] In 1931 Henry Weed Fowler placed it in the genus Rhyncopelates of which it is the only species.
