Neosauropoda is a division-level clade of sauropods within Dinosauria, and consists of the group leading to Diplodocoidea and Macronaria. Haplocanthosaurus was a typical basal neosauropod from around 150 million years ago, in the Late Jurassic. Many later sauropods, including Diplodocus, Apatosaurus, and Brachiosaurus, were also neosauropods by definition.

The clade was originally coined by Argentine paleontologist José Bonaparte in 1986.
