鼠茅（学名：Vulpia myuros）为禾本科鼠茅属下的一个种。

Vulpia myuros, the annual fescue, or rat's-tail fescue, is an annual grass species of the genus Vulpia. It was probably originally native to Eurasia, but it can now be found nearly worldwide as a naturalized species.

In the United Kingdom it forms dense, even swards of fine, hair-like stems in recently disturbed habitats, such as 3-10-year-old pulverised fuel ash. It is typically displaced by perennial grasses after about a decade.
