Lolium is a genus of tufted grasses in thebluegrass subfamily of the grass family. It is often called ryegrass, but this term is sometimes used to refer to grasses in other genera.



Lolium contains some species which are important grasses for both lawns, and as pasture and for grazing and hay forlivestock, being a highly nutritious stock feed. Ryegrasses are also used in soil erosion control programs. It is the principal grazing grass in New Zealand where some 10 million kilograms of certified seed are produced every year. There is a large range of cultivars. The primary species found worldwide and used for both lawns and as a forage crop is perennial ryegrass(Lolium perenne). Like many cool-season grasses of the Poaceae, it harbors a symbiotic fungal endophyte, either Epichloë or its close relative Neotyphodium, both of which are members of the fungal family Clavicipitaceae.

Some species, particularly L. temulentum, are weeds which can have a severe impact on the production of wheat and other crops. Ryegrass pollen is also one of the major causes of hay fever. Tennis courts, including those at the All England Lawn Tennis and Croquet Club, the venue for Wimbledon, are sometimes planted in ryegrass mixes, depending on the tournament. Glyphosate-resistant Lolium has been reported from Mississippi in 2006
