The Diamond D-JET is a composite, five-seat, single-engine jet aircraft developed by Diamond Aircraft Industries. The intended cost was advertised as US$1.89 million dollars in March 2009.

By February 2013 the aircraft's development program was suspended pending company reorganization and the D-Jet workforce had been laid off. In May 2014 the company confirmed that the project remained suspended, but not cancelled.

The December 2016 sale of a majority share of Diamond Aircraft Canada to Wanfeng Aviation of China will result in a re-assessment of the D-Jet program for possible resumption of development.

Diamond targeted the design at the owner-pilot market, seeing it as more practical for single-pilot operations than the Eclipse 500 and the Cessna Citation Mustang. By limiting the altitude to 25,000 feet, pressurization failures would be less critical emergencies, too. Diamond intends the D-JET to have a lower operating cost than other very light jets.

On November 9, 2006, at the AOPA Expo in Palm Springs, California, United States, Diamond announced that ATP Flight School (ATP) had placed the first fleet order for 20 Diamond D-JETs. The intention at that time was that ATP would provide factory-approved training to D-JET purchasers beginning in 2008. Toronto-based Chartright Air Group ordered 10 D-JET aircraft with expected delivery beginning 2010.

In February, 2008 Diamond announced that the aircraft will be built in a new plant in London, Ontario, Canada. This announcement came after the Government of Canada announced it was giving the company a “Cdn$19.6 million strategic, repayable investment” and the Government of Ontario announced that it had given the company Cdn$11 million. Diamond claims that research and development costs for the D-JET have been Cdn$95.2 million and that the plant to build the aircraft will cost an additional $100 million.
