A fish hook or fishhook is a tool for catching fish either by impaling them in the mouth or, more rarely, by snagging the body of the fish. Fish hooks have been employed for millennia by anglers to catch fresh and saltwater fish. In 2005, the fish hook was chosen by Forbes as one of the top twenty tools in human history. Fish hooks are normally attached to some form of line or lure which connects the caught fish to the angler. There is an enormous variety of fish hooks in the world of fishing. Sizes, designs, shapes, and materials are all variable depending on the intended purpose of the fish hook. Fish hooks are manufactured for a range of purposes from general fishing to extremely limited and specialized applications. Fish hooks are designed to hold various types of artificial, processed, dead or live baits (bait fishing); to act as the foundation for artificial representations of fish prey (fly fishing); or to be attached to or integrated into other devices that represent fish prey (lure fishing).

Hooks are designed as either single hooks—a single eye, shank and point; double hooks—a single eye merged with two shanks and points; or triple—a single eye merged with three shanks and three evenly spaced points. Double hooks are formed from a single piece of wire and may or may not have their shanks brazed together for strength. Treble hooks are formed by adding a single eyeless hook to a double hook and brazing all three shanks together. Double hooks are used on some artificial lures and are a traditional fly hook for Atlantic Salmon flies, but are otherwise fairly uncommon. Treble hooks are used on all sorts of artificial lures as well as for a wide variety of bait applications.

A fishing lure is a type of artificial fishing bait which is designed to attract a fish's attention. The lure uses movement, vibration, flash and color to bait fish. Many lures are equipped with one or more hooks that are used to catch fish when they strike the lure. Some lures are placed to attract fish so a spear can be impaled into the fish or so the fish can be captured by hand. Most lures are attached to the end of a fishing line and have various styles of hooks attached to the body and are designed to elicit a strike resulting in a hookset. Many lures are commercially made but some are hand made such as fishing flies. Hand tying fly lures to match the hatch is considered a challenge by many amateur entomologists.
Modern commercial lures usually are often used with a fishing rod and fishing reel but there are some who use a technique where they hold the line in their hands. Handlining is a technique in which the line is held directly in the hands versus being fed through the guides of a fishing rod. Longlining also can employ lures to catch fish. When a lure is used for casting, it is continually cast out and retrieved, the retrieve making the lure swim or produce a popping action. A skilled angler can explore many possible hiding places for fish through lure casting such as under logs and on flats.
