Psocidae is a family of barklice in the order Psocodea (formerly Psocoptera).

[1] Members of this family are recognized by their wing-venation, where the areola postica is fused to the M-vein, giving rise to the so-called discoidal cell.

This family is closely related to Myopsocidae.

The family is widespread, including New Zealand.
