Abstract: A brief review is given of various dark matter candidates. In particular, some of the most studied candidates like axions, inert Higgs doublet, sterile neutrinos, supersymmetric particles and Kaluza‐Klein particles are discussed. In particular, indirect detection methods are reviewed, with gamma‐ray detection being a particularly important method. The situation also for indirect detection through antimatter cosmic rays has recently become quite interesting with new results having dark matter as one of the possible explanations. Problems of this explanation and possible solutions are discussed, and the importance of new measurements is emphasized. If the explanation is indeed dark matter, some unusual and unexpected properties would be needed. One should always keep the possible “conventional” astrophysical explanations, like electron and positron radiation from pulsars in mind. To get a conclusive case for dark matter, detection in other channels will likely be needed, such as direct detection or detection of angular and spectral signatures in gamma‐rays.
