Delivery is the process of transporting goods from a source location to a predefined destination. Cargo (physical goods) is primarily delivered via roads and railroads on land, shipping lanes on the sea, and airline networks in the air. Certain types of goods may be delivered via specialized networks, such as pipelines for liquid goods, power grids for electrical power and computer networks such as the Internet or broadcast networks for electronic information. Car transport is a particular subgroup; a related variant is Autorack, which involves transport of autos by railroads.

Delivery is a fundamental component of commerce and trade, and involves transport and distribution. The general process of delivering goods is known as distribution, while the study of effective processes for delivery and disposition of goods and personnel is called logistics. Firms specializing in delivering commercial goods from the point of production or storage to their point of sale are generally known as distributors, while those that specialize in the delivery of goods to the consumer are known as delivery services. Postal, courier, and relocation services also deliver goods for commercial and private interests.
