Orientus ishidae, common name Japanese leafhopper or Mosaic leafhopper, is a species of leafhoppers belonging to the family Cicadellidae subfamily Deltocephalinae.

The adults reach 4.5–6.5 millimetres (0.18–0.26 in) of length. This leafhopper shows a distinctive mosaic-like pattern on the forewings and an orange band between the eyes. Orientus ishidae is associated with willow (Salix species), hornbeam (Carpinus betulus) and with many woody plants and deciduous trees. It may cause serious leaf damages to several tree species and is implicated as a vector of the phytoplasmic flavescence dorée (FD) disease in vineyards. Adults can be found from June to October.
The nymphs are strongly coloured, the patterning is variable. They often adopt a tail-up posture in response to danger, as seen on the left.
