The Faboideae are a subfamily of the flowering plant family Fabaceae or Leguminosae.

An acceptable alternative name for the subfamily is Papilionoideae, or Papilionaceae when this group of plants is treated as a family.

Faboideae may be trees, shrubs, or herbaceous plants.

The pea-shaped flowers are characteristic of the Faboideae subfamily and root nodulation is very common.

Modern molecular phylogenetics recommend a clade-based classification of Faboideae as a superior alternative to the traditional tribal classification of Polhill:[5][22][23][24][25] Angylocalyceae Dipterygeae Amburaneae Swartzioids Atelioids Cladrastis clade Exostyleae Ormosieae Brongniartieae Leptolobieae Camoensieae Sophoreae Podalyrieae Crotalarieae Genisteae Vataireoids Andira clade Amorphoids Daleoids Adesmia clade Dalbergia clade Pterocarpus clade Baphieae Hypocalypteae Mirbelioids Indigofereae Barbierieae (Clitoriinae clade) Abreae Millettieae Diocleae Kennediinae clade Desmodieae Cajaninae clade Erythrininae clade Psoraleeae Phaseoleae clade Loteae Sesbanieae Robinieae Wisterieae Fabeae Hedysareae Astragaleae Note: Minor branches have been omitted.
