Halocypridina is a suborder of seed shrimp in the order Halocyprida.

Ostracods of this group often have a dorsoposterior spine on the carapace.

[2] The adductor muscle scars show various patterns, in contrast to those of the Cladocopina, which are in a triangular pattern (three scars) or a half-rosette (15 scars).

[2] A sixth limb is present (absent in Cladocopina).

The group is divided into the Halocypridae and the Thaumatocyprididae.
