Brachylaena is a genus of flowering plants in the aster, or composite, family, Asteraceae or Compositae. Several are endemic to Madagascar, and the others are distributed in mainland Africa, especially the southern regions.
These are trees and shrubs with alternately arranged leaves. One of these, Brachylaena merana of Madagascar, is the tallest of all composites ('daisy trees") at up to , and Brachylaena huillensis of East Africa is of similar height (but see also Strobocalyx arborea). They are dioecious, with male and female flowers occurring on separate individuals. The flower heads are somewhat disc-shaped. Heads with female flowers are larger and produce larger pappi.
B. huillensis is the only widespread species, growing as a dominant tree in Brachylaena woodlands and a common species in some eastern African forests. It provides critical habitat for many animal species. It is also sought after for its wood and has been overexploited.
Some species are subject of dispute:
