The Irkut MC-21 is a twin-engine short- to mid-range Russian jet airliner with a capacity of 150-212 passengers. The MC-21 is being developed and to be produced by Irkut and Yakovlev Design Bureau of the United Aircraft Corporation (UAC) group. It was formerly known in English as MS-21; Russian: МС‑21 "Магистральный Самолёт 21 века" – "Magistralny Samolyot 21 veka" – "Airliner of the 21st Century".

The design is based on the never-realized, twin-engine Yakovlev Yak-242 as a development of the three-engine Yakovlev Yak-42. According to a recent statement made by Russian deputy premier Dmitry Rogozin, the name of the MC-21 serial production aircraft will again be Yak-242.

Intended to become a competitor of Airbus A320neo, Boeing 737 MAX, Bombardier CSeries, also replace the remainders of Yakovlev Yak-42, Tupolev Tu-134, Tupolev Tu-154, and Tupolev Tu-204/214s in service, the MC-21 certification and delivery was initially planned by 2016, but later delayed to the end of 2018.

The initial design is to include composite materials (about 33%), increasing to 40-45% provided a composite wing is added in 2015. In March 2008, a contract was signed which will see Sukhoi Civil Aircraft Company, a subsidiary of Sukhoi Corporation, designing and manufacturing composite wings for the aircraft. Engines supplied for the Russian domestic market will be the Aviadvigatel PD-14. In December 2009, Pratt & Whitney announced that the Irkut Corporation had selected the PW1000G engine to power the MC-21. On 20 August 2009, Hamilton Sundstrand, a subsidiary of United Technologies Corporation, announced they had signed a $2.3 billion deal with Irkut to supply systems for the MC-21. Irkut also selected Rockwell Collins and its Russian partner Avionika to supply the MC-21's avionics.Goodrich also a subsidiary of United Technologies Corporation, along with Aviapribor, secured the mandate to develop an integrated control system for the MC-21. The Interior will feature furnishings from Zodiac Aerospace, coordinated from C&D Zodiac in Huntington Beach, California. The Water and Waste Systems of the aircraft will incorporate innovations from Zodiac Aerospace in Carson, California.
