史氏指虾蛄（学名：Gonodactylus smithii）为指虾蛄科指虾蛄属下的一个种。

Gonodactylus smithii, the purple spot mantis shrimp, is a species of mantis shrimp of the smasher type. It is found from New Caledonia to the western part of the Indian Ocean, including Australia's north coast and the Great Barrier Reef.

It is the only organism known to simultaneously detect the four linear and two circular polarization components required for Stokes parameters, which yield a full description of polarization. It is thus believed to have optimal polarization vision.
