Recent progress in polarized ion sources development is reviewed. New techniques for production of polarized
ion beams are discussed. Feasibility studies of these techniques are in progress at BNL and other laboratories. Polarized deuteron beams will be required for the polarization program at the Dubna Nuclotron and at the deuteron Electric Dipole Moment experiment at BNL. Experiments with polarized
ion beams are a part of the experimental program at the future Electron Ion Collider.
