A chocolate chip is a small piece or chunk of chocolate that is typically used as an ingredient in baking, most famously in chocolate chip cookies. Chocolate chips are also popular in a variety of other desserts and snacks such as muffins, pancakes, ice creams, and granola bars. They are generally small, flat-bottomed teardrop shapes, though they can come in various sizes and forms, including chunks and mini chips.

Chocolate chips were originally made from semi-sweet chocolate, but today they are available in many varieties such as milk chocolate, dark chocolate, white chocolate, and flavored versions like mint and butterscotch. The concept of chocolate chips and the chocolate chip cookie originated in the United States in the 1930s, credited to Ruth Graves Wakefield, who added pieces of chocolate to her cookie dough. The idea quickly became popular, leading to the commercial production of chocolate chips.
