A milk float is a vehicle specifically designed for the delivery of fresh milk. Today, milk floats are usually battery electric vehicles (BEV), but they were formerly horse-drawn floats. They were once common in many European countries, particularly the United Kingdom, and were operated by local dairies. However, in recent years, as the number of supermarkets, small independent grocers and petrol stations, and convenience stores stocking fresh milk has increased, many people have switched from regular home delivery to obtaining fresh milk from these other sources.

Delivery is the process of transporting goods from a source location to a predefined destination. Cargo 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 the transport of autos by railroads.
