Mars Inc. is an American multinational manufacturer of confectionery, pet food, and other food products and a provider of animal care services, with US$45 billion in annual sales in 2022; that year Forbes ranked the company as the fourth-largest privately held company in the United States. Headquartered in McLean, Virginia, the company is entirely owned by the Mars family. Mars operates in four business segments around the world: Mars Wrigley Confectionery, Petcare, Food, and MARS Edge, the company's life sciences division.

Pet food is animal feed intended for consumption by pets. Typically sold in pet stores and supermarkets, it is usually specific to the type of animal, such as dog food or cat food. Most meat used for animals is a byproduct of the human food industry, and is not regarded as "human grade".
