Traquairaspis is a genus of extinct heterostracan agnathan fish known from the Silurian and Early Devonian periods.

It is predominantly known from Late Silurian fluvial deposits from Wales and England: some species were also found in shallow water marine environment in Canada and North America.

[1] The head-shield and body armor of most species form an almond shape.

This similarity of ornamentation creates much confusion over the taxonomical placement of Weigeltaspis, in addition to confusion over whether or not an isolated plate is of Traquairaspis, or of Weigeltaspis.
