We present a general classification of minimal models where the Dark Matter coannihilates with another particle X. Besides this new particle, such coannihilation processes typically require the existence of a mediator, M. Assuming tree-level and renormalizable interactions, we construct all the possible combinations of Dark Matter, X and M that respect gauge and Lorentz invariance. Our framework allows to identify the main categories of LHC signatures associated with coannihilation. We discuss the different aspects of these signatures, with an emphasis on new possible topologies that could be explored at colliders. We briefly comment on constraints arising from relic abundance as well as from direct and indirect detection.
