Wing Commander III: Heart of the Tiger (commonly abbreviated WC3, WCIII, or HOTT) is the second sequel in Chris Roberts' Wing Commander science fiction space combat simulation franchise of computer games, produced by Origin Systems. Released in 1994, Wing Commander III made the move from the sprite-based graphics used in previous titles to software-driven texture-mapped polygonal 3D.

WC3 featured an entirely new line of ships and fighters, abandoning the technology of Wing Commander and Wing Commander II. Terran craft were redesigned from "airplanes in space", while Kilrathi craft were totally redesigned into asymmetrical ships with prongs, barbs and fang-like surfaces. The new, blockier forms were made necessary by the then-primitive state of polygon graphics, as WC3 was released a few years before the first true 3D video cards and all 3D effects had to be calculated by the CPU.
