Metal–organic　frameworks　(MOFs)　are　a　class　of　crystalline　micro/mesoporous　hybrid　materials　composed　of　metal　ions　or　metal　clusters　interconnected　by　organic　linkers.　MOFs　are　recently　emerging　as　a　new　type　of　photoactive　materials　for　different　photocatalytic　applications　due　to　their　unique　structural　characteristics.　In　this　chapter,　the　fundamentals　of　MOFs　for　photocatalysis　and　the　photoexcitation　pathways　over　MOF-based　photocatalysts　are　briefly　introduced.　Examples　of　using　MOFs　for　different　photocatalytic　reactions,　including　photocatalytic　water　reduction/oxidation,　CO2　reduction,　environmental　remediation,　and　organic　transformations,　are　summarized.　Strategies　for　designing　and　developing　MOFs　as　efficient　photocatalysts　and　for　expanding　their　photocatalytic　applications　are　also　demonstrated.　Finally,　the　limitations,　challenges,　and　the　future　perspective　of　the　application　of　MOFs　for　photocatalysis　are　addressed.　The　objective　of　this　chapter　is　to　encourage　more　future　efforts　to　be　devoted　to　design　and　development　of　new　efficient　MOFs　with　wide　applications　in　photocatalysis.　©　2020　Elsevier　Ltd
