Iridium‐catalyzed C−H activation and cyclization of naphthalen‐1‐amines with diazo compounds leading to naphtho[1,8‐bc]pyridines have been developed. Different from the previous free‐amine‐directed C−H functionalization with diazo compounds that relied on the coordination of lone pair electrons or in situ formation of imine, this transformation passes through a five‐membered iridacycle intermediate containing an
