Oryzoideae (syn. Ehrhartoideae) is a subfamily of the true grass family Poaceae. It includes around 120 species in 20 genera, notably the major cereal crop rice.[1] Within the grasses, this subfamily is one of three belonging to the species-rich BOP clade, which all use C3 photosynthesis; it is the basal lineage of the subfamily.[2][3]

It contains four tribes and one genus of unclear position (incertae sedis), Suddia (probably Phyllorachideae).[1] Phylogenetic analyses have resolved the branching order of these clades within the subfamily:[1]
