Shō Gen (尚元, 1528–1572) was king of the Ryukyu Kingdom from 1556 to 1572.

His reign marked the beginning of the council's demonstration of significantly greater effectiveness and efficiency than previously.

The Shimazu wished to establish some control over the Ryukyus, making them either a tributary or a vassal state.

The kingdom resisted the Shimazu overtures, and a small punitive mission launched by the Shimazu created a small skirmish on the island of Amami Ōshima in 1571, although the Ryukyuans defeated them.
