Robinson R44 je mali, lagani civilni helikopter s četiri sjedišta kojeg proizvodi Robinson Helicopter Company od 1992. godine. Dvokraki rotor pokreće klipni motor s šest cilindara. Iako je slian ranijem Robinson R22, R44 je veći i brži od svojih prethodnika. Opremljen je sa servo-mehanizam komandi leta što nije bila značajka na R22.
R-44 je jednomotorni helikopter s polu-krutim dvokrakim glavnim rotorom, dvokrakim repnim rotorom i skijama kao podvozje. U kabinu s dva reda usporednih sjedećih mjesta uz pilota stane još tri osobe.
Smjer rotacije repnog rotora na R44 je obrnut u odnosu na R22 s čim se poboljšala kontrola okretanja helikoptera.

The R44 is a single-engined helicopter with a semi-rigid two-bladed main rotor, a two-bladed tail rotor and a skid landing gear. It has an enclosed cabin with two rows of side-by-side seating for a pilot and three passengers. Tail rotor direction of rotation on the R44 is reversed compared to the R22 for improved yaw control authority. On the R44 the advancing blade is on the bottom.
