Gum arabic, also known as acacia gum, is a natural plant-derived gum produced from the dried sap of several species of acacia trees. Gum arabic is predominantly collected from two related species, namely Acacia senegal and Vachellia (Acacia) seyal. Producers harvest the gum commercially from wild trees, mostly in Sudan (80%).

Gum arabic is used primarily in the food industry as a stabilizer. It is edible and has E number E414. Gum arabic is a key ingredient in traditional lithography and is used in printing, paint production, glue, cosmetics and various industrial applications, including viscosity control in inks and in textile industries, though less expensive materials compete with it for many of these roles.
