A regiodivergent and stereoselective transition‐metal‐catalyzed addition of 4‐pyridones to allenes furnishing N‐allylated pyridones is reported. Employing a commercially available chiral rhodium catalyst enabled enantioselective branched‐selective allylation. Conversely, an achiral palladium catalyst led to linear‐selective N‐allylation in high E‐selectivities. A wide range of functional groups was
