Ziziphus is a genus of spiny shrubs and small trees in the buckthorn family, Rhamnaceae. It includes 68 species native to tropical and subtropical Africa, Eurasia, and Australia and tropical South America. The leaves are alternate, entire, with three prominent basal veins, and often aromatic. The flowers are small, inconspicuous yellow-green. The fruit is an edible drupe, often very sweet and sugary, reminiscent of a date in texture and flavour.

Well known species include the commonly cultivated Ziziphus jujuba (jujube), Ziziphus spina-christi from southwestern Asia, Ziziphus lotus from the Mediterranean region, and ber (Ziziphus mauritiana), which is found from western Africa to India.
