Abstract: Basic properties of Regge poles are reviewed. The Regge poles are considered from both t-channel and s-channel points of view. The main part of the review is devoted to the Regge poles in QCD. The method of the Wilson-loop path integral is used to calculate trajectories of the Regge poles for 
and gluonic states. The problem of the pomeron in QCD is discussed in detail. It is shown how to use the 1/N expansion for classification of the reggeon diagrams in QCD. The role of Regge cuts in reggeon theory is discussed and their importance for high-energy phenomenology is emphasized. Models based on the reggeon calculus, 1/N expansion in QCD, and string picture of interactions at large distances are reviewed and applied to a broad class of phenomena in strong interactions. It is shown how to apply the reggeon approach to small-x physics in deep inelastic scattering.
