Polariton lasing is a new type of lasing that realizes ultra-low threshold lasing with the coherence of Bose-Einstein condensation (BEC) of exciton-polariton in semiconductors. Unlike conventional 3-D organic and inorganic materials, 2-D transition metal dichalcogenides and 2-D perovskite show great potential in the further development of polariton lasing due to their high exciton binding energies, high oscillator strengths, direct band gaps, van der Waals properties, and valley polarization properties, which are conducive to the realization of strong coupling of exciton and cavity modes and BEC of exciton-polariton. In this review, the principle and progress of polariton lasing in 2-D transition metal chalcogenides and perovskite were mainly focused on, starting with development of strong coupling between exciton and cavity modes. Then, the modulation of the coherence of polariton, the realization of the BEC and polariton lasing was introduced. Finally, an outlook will be given on the future development of polariton lasing in 2-D materials.
