  We review theories of Asymmetric Dark Matter (ADM), their cosmological
implications and detection. While there are many models of ADM in the
literature, our review of existing models will center on highlighting the few
common features and important mechanisms for generation and transfer of the
matter-anti-matter asymmetry between dark and visible sectors. We also survey
ADM hidden sectors, the calculation of the relic abundance for ADM, and how the
DM asymmetry may be erased at late times through oscillations. We consider
cosmological constraints on ADM from the cosmic microwave background, neutron
stars, the Sun, and brown and white dwarves. Lastly, we review indirect and
direct detection methods for ADM, collider signatures, and constraints.
