Highly selective tandem nucleophilic addition/cross‐coupling reactions of alkynes have been developed usingvisible‐light‐promoted dual gold/photoredoxcatalysis. The simultaneous oxidation of AuI and coordination of the coupling partner by photo‐generated aryl radicals, and the use of catalytically inactive gold precatalysts allows for high levels of selectivity for the cross‐coupled products without
