The subfamily Dialioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees and shrubs. The subfamily consists of 17 genera, which are widespread throughout the tropics. It has the following clade-based definition:

The most inclusive crown clade containing Poeppigia procera C.Presland Dialium guianense (Aubl.) Sandwith, but not Cercis canadensis L., Duparquetia orchidacea Baill., or Bobgunnia fistuloides (Harms) J. H. Kirkbr. & Wiersema[1]

Members of the family also share the following morphological characteristics: the presence of cymose inflorescences, the absence of vestured pits in the xylem, and a high degree of organ loss.[2][3]
