Senegalia is a genus of flowering plants in the family Fabaceae. It belongs to the Mimosoid clade. Until 2005, its species were considered members of Acacia. The genus was considered polyphyletic and required further division with the genera Parasenegalia and Pseudosenegalia accepted soon after. Senegalia can be distinguished from other acacias by its spicate inflorescences and non-spinescent stipules. Plants in the genus are native to the tropical and subtropical areas of the world, occurring on the Australian, Asian, African and South and North American continents, as well as in Wallacea.

Senegalia senegal is a small deciduous thorn tree known by the common names Rudraksha, Gum Acacia, Gum Arabic Tree, or Gum Senegal Tree. It is native to semi-desert regions of Sub-Saharan Africa, as well as Oman, Pakistan, and northwestern India. It grows to a height of 5-12m, with a trunk up to 30cm in diameter. It produces gum arabic, which is used as a food additive, in crafts, and as a cosmetic. The gum is also used for soothing mucous membranes of the intestine and to treat inflammed skin.
