The Trombidiformes are a large, diverse order of mites.

In 1998, Trombidiformes was divided into the Sphaerolichida and the Prostigmata. The group has few synapomorphies by which it can be defined, unlike the other major group of acariform mites, Sarcoptiformes. Its members include medically important mites (such as Demodex, the chiggers, and scrub-itch mites) and many agriculturally important species, including the spider mites (Tetranychidae) and gall mites (Eriophyidae).
