Iridopelma is a genus of Brazilian tarantulas that was first described by Reginald Innes Pocock in 1901.

Avicularia and Typhochlaena both own the latter characteristics; however, Iridopelma can be distinguished from Avicularia by the spermatheca, which lacks a curvature, and from Typhochlaena by the spinnerets, which are finger-shaped.
it contains six species, all found in Brazil:
