Oryctorhynchus is an extinct genus of rhynchosaur from the Late Triassic (Carnian-Norian)-aged Wolfville Formation of Nova Scotia, Canada that may have been the same animal as Beesiiwo. The type species, O. bairdi, was named and described in 2020. It was originally seen as a species of Hyperodapedon until 2020.

Shortly after, it was informally named the "Nova Scotia Hyperodapedon" (H. sp.) by Robin Whatley in a 1984 paper published by J. A. Hopson. It was briefly described by Michael Benton (1983) also as a species of Hyperodapedon. It was then assigned to cf. "Hyperodapedon" sanjuanensis by Lucas et al., (2002). The genus was not recognised as a distinct taxon until it was named in 2020.
