We review the theory and phenomenology of models in which the dark matter is made of composite pseudo-Nambu Goldstone bosons. We focus predominantly on models in which the Higgs is also composite and dark matter is a singlet and heavier than the Standard Model fields. Then we discuss a variety of departures from this main setup, including: electroweak charged dark matter, lighter dark matter, issues related to quantum anomalies, ultraviolet completions or composite dark matter not related to the hierarchy problem.
