Haplocheirus is a genus of alvarezsauroid theropod dinosaur. It is the earliest member of its clade. It is the oldest known alvarezsauroid, predating all other members by about 63 million years. Haplocheirus was described in 2010 from a fossil specimen found from the 160-million-year-old Shishugou Formation in the Junggar Basin of northwestern China. The type species is H. sollers, meaning "simple-handed skillful one", referencing its hypothesized behavior of using its three-fingered hands for activities other alvarezsauroids couldn't, such as catching prey.
