The Fig Newton is a brand of fig bar (in Europe, fig roll), pastry filled with fig jam. A trademarked product of Nabisco, Fig Newtons in their modern form originated in the United States and have since spread across the world. Their unusual shape is a characteristic that has been adopted by many competitors, such as the generic fig bars sold by most supermarkets, and Newman's Own Fig Newmans (an organic variety).

Nabisco makes several varieties of the Newton, including Strawberry, Cherries 'n' Cheesecake, Caramel Apple, Raspberry, Cherry, Blueberry, Grape, and Isaac Newtons, in addition to the original Fig. The original Fig Newton also comes in a low fat variety and a 100% whole grain variety. Fig Newton Minis were also recently introduced. The fig bar is the company's number-three seller at more than a billion a year. Newer packs of Newton products have a "snack and seal" container to keep the contents fresh.
