Caesalpinioideae es el nombre botánico de la Subfamilia, que pertenece a la Familia Fabaceae o Leguminosae. El nombre proviene del género tipo Caesalpinia.
Las cesalpinoideas están distribuidas por el trópico. Sus flores son zygomorfas y muy variables.
La distribución geográfica y el estatus del grupo es controversial.
Although the group as such is well recognised, there are a number of genera whose placement (here, or in one of the two other subfamilies) is not generally agreed on. In some classifications, for example the Cronquist system, the group is recognized at the rank of family, Caesalpiniaceae. Recent systematic research, using molecular data, has shown the group to be paraphyletic with respect to subfamilies Faboideae (Papilionoideae) and Mimosoideae and a split is being considered.
