The Saab JAS 39 Gripen (English: The Griffin) is a light single-engine supersonic multirole fighter aircraft manufactured by the Swedish aerospace and defence company Saab AB. The Gripen has a delta wing and canard configuration with relaxed stability design and fly-by-wire flight controls. Later aircraft are fully NATO interoperable. As of 2020, more than 271 Gripens of all models, A–F, have been delivered.

In 1979, the Swedish government began development studies for "an aircraft for fighter, attack, and reconnaissance" (ett jakt-, attack- och spaningsflygplan, hence "JAS") to replace the Saab 35 Draken and 37 Viggen in the Swedish Air Force. A new design from Saab was selected and developed as the JAS 39. The first flight took place in 1988, with delivery of the first serial production airplane in 1993. It entered service with the Swedish Air Force in 1996. Upgraded variants, featuring more advanced avionics and adaptations for longer mission times, began entering service in 2003.

To market the aircraft internationally, Saab formed partnerships and collaborative efforts with overseas aerospace companies. On the export market, early models of the Gripen achieved moderate success, with sales to nations in Central Europe, South Africa, and Southeast Asia. Bribery was suspected in some of these procurements, but Swedish authorities closed the investigation in 2009.

A major redesign of the Gripen series, previously referred to as Gripen NG (Next Generation) or Super JAS, now designated JAS 39E/F Gripen began deliveries to the Swedish Air Force and Brazilian Air Force in 2019. Changes from the JAS C to JAS E include a larger fuselage, a more powerful engine, increased weapons payload capability, and new cockpit, avionics architecture, electronic warfare system and other improvements.
