Triozidae is one of seven families collectively referred to as plant lice. They have traditionally been considered part of a single family, Psyllidae, but recent classifications divide the group into a total of seven families; most of the genera (over 70) remain in the Psyllidae, but Triozidae is the third-largest family in the group.

The family contains a number of agricultural pest species including:

• Baeoalitriozus diospyri, the persimmon psyllid
• Bactericera cockerelli, the potato psyllid
• Trioza erytreae, the African citrus psyllid
