'''[[Poaceae]]''', also known as the '''true grasses''', is the fourth largest plant family in the world with around 12,000 species and roughly 800 genera.<ref name="SorengPeterson2015"/><ref>{{Cite web |last=Sánchez |first=Mónica |date=2020-01-22 |title=What are the largest plant families? |url=https://www.jardineriaon.com/en/larger-plant-families.html |access-date=2023-12-14 |website=Jardineria On |language=en}}</ref> They contain, among others, the [[cereal]] crop species and other plants of economic importance, such as the [[bamboos]], and several important [[weed]]s.

Grasses probably originated in the understory of tropical rainforests in the [[Late Cretaceous]], but have since come to occupy a wide range of different habitats.<ref name="EdwardsSmith2010">{{cite journal|last1=Edwards|first1=E.

[[Anomochlooideae]], [[Pharoideae]] and [[Puelioideae]] are early diverging lineages containing only a few species. Most of the diversity falls into the two big [[BOP clade|BOP]] and [[PACMAD clade|PACMAD]] clades, which each contain roughly half of the family's species. C<sub>4</sub> lineages have only evolved in the PACMAD clade, whereas many lineages in the BOP clade have evolved adaptations to cold climate.

While the higher-level classification of the grasses is now relatively well understood, taxonomic efforts continue at the species and genera level, and with continuing phylogenetic research, a number of names is likely to change.<ref name=VorontsovaSimons2012>{{cite journal |last1=Vorontsova|first1=Maria S. |last2=Simon |first2=Bryan K. |title=Updating classifications to reflect monophyly: 10 to 20 percent of species names change in Poaceae |journal=Taxon |volume=61 |issue=4 |year=2012 |pages=735–746|url=https://www.researchgate.net/publication/260285689|doi=10.1002/tax.614003 |bibcode=2012Taxon..61..735V }}</ref> The list of genera below is therefore likely to evolve with further study.
