There are 1085 species of Acacia accepted by Plants of the World Online as at December 2024, with species native to Australia, New Guinea, Southeast Asia, Hawaii and the Mascarene Islands, and introduced to other countries.
An older concept of Acacia included about 1350 species from Australia, Africa, tropical America and Asia, but following decisions made at the 2011 International Botanical Congresses, the name Acacia was reserved for species found in Australia, New Guinea and Southeast Asia.
Some species, previously included in Acacia and distributed in the Indian Ocean, tropical Asia and tropical America are now classified under:
- Vachellia 157 species (pantropical)
- Senegalia 220 species (pantropical)
- Parasenegalia: 11 species (South America)
- Pseudosenegalia: 2 species (Bolivia)
- Acaciella : 15 species (Americas)
