The Mikoyan-Gurevich DIS (Russian: Дальний истребитель сопровождения/ Dalnij Istrebitel' Soprovozhdenya – "long-range escort fighter") was a prototype Soviet heavy fighter of World War II, envisioned to serve primarily in the escort fighter role. The service designation MiG-5 was reserved for the production version of the aircraft. Competing designs in the USSR included the Grushin Gr-1, Polikarpov TIS and Tairov Ta-3.

It was intended to develop reconnaissance and bomber versions but these plans were disrupted by Operation Barbarossa, the German invasion in June 1941. The project failed due to its disappointing Mikulin AM-37 engines and when a second prototype was built with M-82 radial engines its performance was mediocre. The design was cancelled in 1943 after at least two prototypes had been built.
