In marketing, a product is anything that can be offered to a market that might satisfy a want or need. In retailing, products are called merchandise. In manufacturing, products are purchased as raw materials and sold as finished goods. Commodities are usually raw materials such as metals and agricultural products, but a commodity can also be anything widely available in the open market.

The noun product is "a thing produced by labor or effort". Since 1575, the word "product" has referred to anything produced. Since 1695, the word has referred to "thing or things produced". The economic or commercial meaning of product was first used by political economist Adam Smith.

In general usage, product may refer to a single item or unit, a group of equivalent products, a grouping of goods or services, or an industrial classification for the goods or services.
