Ceratonia siliqua, commonly known as the carob tree (from Arabic خَرُّوبٌ kharrūb and Hebrew חרוב haruv), St. John's-bread, or locust bean or simply locust-tree, is a species of flowering evergreen shrub or tree in the pea family, Fabaceae. It is widely cultivated for its edible pods, and used as an ornamental tree or grown in large carob orchards. The ripe, sweet dried pod is often ground into carob powder, which is used to replace cocoa-cacao powder.
