Fish fingers or fish sticks are a processed food made using a whitefish, such as cod, hake, haddock, or pollock, which has been battered or breaded. They are commonly available in the frozen food section of supermarkets. They can be baked in an oven, grilled, shallow fried, or deep-fried.

Whitefish or white fish is a fisheries term for several species of demersal fish with fins, particularly Atlantic cod, whiting, haddock, hake (Urophycis), and pollock (Pollachius), among others. Whitefish (Coregonidae) is also the name of several species of Atlantic freshwater fish.
