Ruthenium‐catalyzedmeta‐C−H activation of arenes at roomtemperature is reported to proceed under blue‐light irradiation. A variety of heteroarenes are compatible with this photochemical process, which leads to the corresponding meta C−C coupling products in good to very good yields. Initial mechanistic studies suggest a single‐electron transfer process occurs between a photoexcited RuII‐cyclometalated
