凌风草属（学名：Briza）是禾本科下的一个属，为一年生或多年生、矮小草本植物。该属共有约20种，分布于北温带和南美。

Briza is a genus of annual and perennial plants in the grass family, native to northern temperate regions of Eurasia, North Africa, and certain islands in the Atlantic.

The group is generally referred to as the quaking grasses because the flowers and seedheads shake on their stalks in the slightest breeze. Some of its members are grown as ornamental plants.
