Oryzoideae (syn. Ehrhartoideae) is a subfamily of the true grass family Poaceae. It has around 120 species in 19 genera, notably including the major cereal crop rice. ^[1] Within the grasses, this subfamily is one of three belonging to the species-rich BOP clade; it is sister to the other two lineages in the clade, Bambusoideae and Pooideae. ^{[2] [3]} All members of the BOP clade use C₃ photosynthesis ^{[2] [3]}

It contains four tribes and one genus of unclear position (incertae sedis): Suddia (thought likely to be in the tribe Phyllorachideae). ^[1] Phylogenetic analyses have resolved the branching order of these clades within the subfamily: ^[1]
