Pediculus is a genus of sucking lice, the sole genus in the family Pediculidae. Pediculus species are ectoparasites of primates.

Species include:1

Humans are the hosts of Pediculus humanus. Chimpanzees and bonobos host Pediculus shaeffi. Various New World monkeys in the families Cebidae and Atelidae host Pediculus mjobergi.2
