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

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.
