Cochlespira is a genus of sea snails, marine gastropod mollusks in the family Cochlespiridae.

[2][3] The species in this genus are characterized by their elongated fusiform spire and a long siphonal canal.

The whorls are tabulated by a sharp recurved spinose or beaded keel, between which and the suture the surface is concave, nearly smooth.

This group is extremely close to Ancistrosyrinx Dall, 1881, the latter differing only by having the anal sulcus at the suture, with no intervening ridge, while the outer margin of the fasciole has an elevated lamella between which and the reflected keel at the shoulder there is an excavated channel.

[5] Species from this genus occur in very deep water in the Indo-West Pacific and off Australia (Queensland).
