AB  - The "marriage" of light (i.e., photon) and matter (i.e., exciton) in 
      semiconductors leads to the formation of hybrid quasiparticles called exciton 
      polaritons with fascinating quantum phenomena such as Bose-Einstein condensation 
      (BEC) and photon blockade. The research of exciton polaritons has been evolving 
      into an era with emergent two-dimensional (2D) semiconductors and photonic 
      structures for their tremendous potential to break the current limitations of 
      quantum fundamental study and photonic applications. In this Perspective, the 
      basic concepts of 2D excitons, optical resonators, and the strong coupling regime 
      are introduced. The research progress of exciton polaritons is reviewed, and 
      important discoveries (especially the recent ones of 2D exciton polaritons) are 
      highlighted. Subsequently, the emergent 2D exciton polaritons are discussed in 
      detail, ranging from the realization of the strong coupling regime in various 
      photonic systems to the discoveries of attractive phenomena with interesting 
      physics and extensive applications. Moreover, emerging 2D semiconductors, such as 
      2D perovskites (2DPK) and 2D antiferromagnetic (AFM) semiconductors, are surveyed 
      for the manipulation of exciton polaritons with distinct control degrees of 
      freedom (DOFs). Finally, the outlook on the 2D exciton polaritons and their 
      nonlinear interactions is presented with our initial numerical simulations. This 
      Perspective not only aims to provide an in-depth overview of the latest 
      fundamental findings in 2D exciton polaritons but also attempts to serve as a 
      valuable resource to prospect explorations of quantum optics and topological 
      photonic applications.
