(Butadiene)iron tricarbonyl is an organoiron compound with the formula (C₄H₆)Fe(CO)₃. It is the simplest and most studied metal complex of butadiene. It is an orange colored oil that freezes just below room temperature. The compound adopts a piano stool structure.^[1]

The complex was first prepared by heating iron pentacarbonyl with the diene.^[2]

Iron(0) complexes of conjugated dienes have been extensively studied. In the butadiene series, (η²-C₄H₆)Fe(CO)₄ and (η²:η²-C₄H₆)(Fe(CO)₄)₂ have been crystallized.^[3] Many related complexes are known for substituted butadienes and related species. The species (η⁴-isoprene)iron tricarbonyl is chiral.^[4] Cyclobutadieneiron tricarbonyl is a related complex.
