The Embraer C-390 Millennium is a medium-size, twin-engine, jet-powered military transport aircraft designed and produced by Brazilian aerospace manufacturer Embraer. It is the heaviest aircraft the company has built to date.

Work on the project began at Embraer during the mid-2000s, with early efforts centred around a conceptual derivative of the E190 jetliner of a similar size to the Lockheed C-130 Hercules. In May 2008, the Brazilian government invested R$800 million (US$440M) in the project's development. In April 2009, Embraer received a $1.5 billion contract from the Brazilian Air Force for two prototypes. The aircraft was initially designated C-390 before changing to KC-390 in early 2011. At the 2011 Paris Air Show, Embraer announced plans to launch a stretched version of the aircraft as a civilian freighter. Partnerships were promptly formed with various other aerospace companies, including FAdeA, ENAER, OGMA, and Boeing. Major subcontractors in the aircraft's manufacturing include Aero Vodochody, BAE Systems, and Rockwell Collins.
