Hypuronector is a genus of extinct drepanosaur reptile from the Late Triassic Lockatong Formation of New Jersey.

The etymology of the name translates as "deep-tailed swimmer from the lake", in reference to its assumed aquatic habits hypothesized by its discoverers.

This makes attempts to reconstruct Hypuronector's body or lifestyle highly speculative and controversial.

Hypuronector has inversely been suggested to be aquatic due to its deep, paddle-like tail and the fact that its remains were found in an ancient lake bottom.

However, several studies on its limb morphology, as well as the rather delicate tail vertebrae without evidence of extensive caudal musculature, rule out an aquatic hypothesis, and it was likely arboreal like other drepanosaurs.
