The Mikoyan-Gurevich Ye-8 was a supersonic jet fighter developed in the Soviet Union, intended to replace the MiG-21 (originally named MiG-23).

The original MiG-21's air intakes were moved under the fuselage, freeing up the nose where a larger and more powerful radar, able to deliver longer range air-to-air missiles, could be built in.

Canards were built to both sides of the nose, in front of the cockpit, (the horizontal stabilizers of MiG-21 were left at their original position).

Due to unsolved technical problems, the aircraft's development was abandoned; some parts were used on the MiG-23, including R-23 missiles and their associated Sapfir-23 radar.
