Majorana zero mode is an exotic quasiparticle excitation with non-Abelian statistics in topological superconductor systems and, can serve as the cornerstone for topological quantum computation, a new type of fault-tolerant quantum computation architecture. This chapter highlights recent progress in realizing Majorana modes in iron-based high-temperature superconductors. We begin with the discussion on topological aspect of electronic band structures in iron-based superconductor compounds. Then we focus on several concrete proposals for Majorana modes in this system, including the Majorana zero modes inside the vortex core on the surface of Fe(Te, Se), helical Majorana modes at the hinge of Fe(Te, Se), the Majorana zero modes at the corner of the Fe(Te, Se)/FeTe heterostructure or the monolayer Fe(Te, Se) under an in-plane magnetic field. We also review the current experimental stage and provide the perspective and outlook for this rapidly developing field.
