Forging is a manufacturing process that shapes metal by applying localized compressive forces, typically using a hammer or die, often at elevated temperatures to make the metal more workable. This process is important because it allows manufacturers to create metal parts of varying sizes and specifications for various applications.

thumb|upright=1.4|Hot metal ingot being loaded into a hammer forge thumb|A Semi-finished_casting_products#Billet|billet in an open-die forging press Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons. Forging has been done by smiths for millennia; the traditional products were kitchenware, hardware, hand tools, edged weapons, cymbals, and jewellery.
Since the Industrial Revolution, forged parts are widely used in mechanisms and machines wherever a component requires high strength; such forgings usually require further processing (such as machining) to achieve a finished part. Today, forging is a major worldwide industry.
