Haplocheirus (, from Ancient Greek ἁπλός (haplós), meaning “simple”, and χείρ (kheír), meaning “hand”) is an extinct genus of theropod dinosaur from the Middle Jurassic Shishugou Formation of Xinjiang in China. It is generally considered to be an alvarezsauroid, although some researchers have questioned this assignment. The genus contains a single species, H. sollers, which is known from a mostly complete skeleton including the skull.

The quality of the preservation in the only known specimen of Haplocheirus is near-perfect and preserves the animal in three dimensions. This makes Haplocheirus one of the most well-known Jurassic coelurosaurs from anywhere in the world.
