Bromus madritensis (also, B. matritensis) is a species of brome grass known by the common name compact brome.

It is native to Europe but it has been widely introduced elsewhere, such as North America, where it is found in many areas. It is now known nearly worldwide. This is an annual grass growing solitary or clumped stems to maximum heights between 10 and 50 centimeters. The panicle inflorescence holds spikelets with long awns which vary in color from green to distinctly purplish-red. The species is resistant to dry conditions.

There are two subspecies:

* B. m. ssp. madritensis: panicles less dense, stem and leaf sheath less hairy
* B. m. ssp. rubens (syn. Bromus rubens) - foxtail brome, foxtail chess, red brome: dense panicles and slightly hairy stems
