The Shishugou Formation (simplified Chinese: 石树沟组; traditional Chinese: 石樹溝組; pinyin: Shíshùgōu Zǔ) is a geological formation in Xinjiang, China.

Its strata date back to the Late Jurassic period. Dinosaur remains are among the fossils that have been recovered from the formation.[2] The Shishugou Formation is considered one of the most phylogenetically and trophically diverse Middle to Late Jurassic theropod fauna.[3]

The Wucaiwan Member, once considered a separate, underlying formation,[4] is now considered the lowest unit of the Shishugou Formation.
