Ferroelectric　materials,　characterized　by　the　switchable　spontaneous　polarization　(Ps)　through　reversing　the　directions　of　external　electric　field,　exhibit　versatile　physical　attributes　that　have　been　extensively　used　for　practical　device　applications.　Two-dimensional　(2D)　organic-inorganic　hybrid　perovskites　are　recently　emerging　as　a　robust　family　of　candidate　ferroelectrics,　termed　ferroelectric　semiconductors.　In　particular,　the　coexistence　and/or　coupling　of　ferroelectric　polarization　with　their　semiconducting　properties　enables　new　physical　concepts,　thus　providing　a　potential　platform　for　the　development　of　new　multifunctional　optoelectronic　devices.　This　review　primarily　describes　the　structural　origin　of　symmetry　breaking　for　generating　ferroelectric　orders　in　2D　hybrid　perovskites,　and　then　presents　the　combination　of　ferroelectric　Ps　with　other　semiconducting　optoelectronic　activities.　Regarding　the　emergence　of　new　photoelectric　behaviors,　the　prospects　for　this　2D　family　of　ferroelectric　semiconductors　are　further　discussed,　along　with　their　development　tendency　for　the　future　photoelectronic　device　applications.
