Milo ( MY-loh; stylised as MILO) is a chocolate-flavoured malted powder product produced by Nestlé, typically mixed with milk, hot water, or both, to produce a beverage. It was originally developed in Australia by Thomas Mayne (1901–1995) in 1934.

Most commonly sold as a powder in a green can, often depicting various sporting activities, Milo is available as a premixed beverage in some countries and has been subsequently developed into a snack bar, breakfast cereal and protein granola. Its composition and taste differ from country to country.

Milo maintains significant popularity in a diverse range of countries throughout the world, particularly in Australasia, Asia, Africa, and Latin America.
