The Chengdu J-10 (simplified Chinese: 歼-10; traditional Chinese: 殲-10, NATO Code: Firebird) is a lightweight multirole fighter aircraft capable of all-weather operation, configured with a delta wing and canard design, with fly-by-wire flight controls, and produced by the People's Republic of China's Chengdu Aircraft Corporation (CAC) for the People's Liberation Army Air Force (PLAAF).

The program was authorized by Deng Xiaoping who allocated ¥ 0.5 billion to develop an indigenous aircraft. Work on Project #10 started several years later in January 1988, as a response to the Mikoyan MiG-29 and Sukhoi Su-27 then being introduced by the USSR, and F-15, F-16 already in service in the United States. Development was delegated to the 611 Institute, also known as the Chengdu Aircraft Design Institute and Song Wencong was nominated as the chief designer, as he had previously been the chief designer of the J-7III. The aircraft was initially designed as a specialized fighter, but later became a multirole aircraft capable of both air-to-air combat and ground attack missions.

The J-10 resembles the IAI Lavi The general designer Song Wencong said that J-10 was a development of the indigenous J-9 which preceded the Lavi. This was echoed by a PLAAF's major Zhang Weigang in a 2012 interview.
