Zanclorhynchus is a genus of marine ray-finned fishes belonging to the family Congiopodidae, the pigfishes or horsefishes.

Zanclorhynchus was first described as a genus in 1880 by the German-born British ichthyologist Albert Günther as a monotypic genus, its only member being the new species Günther described in the same paper, Zanclorhynchus spinifer, with its type locality given as Kerguelen Island.

[2] The 5th edition of Fishes of the World classifies this genus in the family Congiopodidae[3] but other authorities classify it within the family Zanclorhynchidae, alongside the genus Alertichthys.

[1] The genus name is a compound of zanklon, which means "sickle", and rhynchus, meaning "snout", assumed to be an allusion to the pointed snout of adult Z.

They have between 8 and 10 spines and 12 and 15 soft rays in the dorsal fin with a deep incision separating the spiny part from the soft rayed part.
