Dairy products are generally defined as foodstuffs produced from milk. A production plant for such processing is called a dairy. Raw milk for processing generally comes from cows, but occasionally from other mammals such as goats, sheep, water buffalo, yaks, or horses.

There are more than 30 main products made from milk with a number of sub-products in each category. Dairy products include:
- Milk, after optional homogenization, pasteurization, in several grades after standardization of the fat level
- Cream, the fat skimmed off the top of milk or separated by machine-centrifuges
- Sour cream, cream that has been fermented by the bacteria Streptococcus lactis and Leuconostoc citrovorum
- Crème fraîche, slightly fermented cream
- Cultured buttermilk, fermented concentrated (water removed) milk using the same bacteria as sour cream
- Milk powder (or powdered milk), produced by removing the water from milk
- Whole milk & buttermilk
- Skim milk
- Cream
- High milk-fat & nutritional powders (for infant formulas)
- Cultured and confectionary powders
- Cream, the fat skimmed off the top of milk or separated by machine-centrifuges

Got Milk? is an international organization supporting dairy products, especially milk.
History
Most dairy products were developed in Europe; the people of that continent have traditionally been the most aggressive in terms of exploiting cattle as a primary food source.
Dairy products were exported to the rest of the world during the imperialism phase of human history. They are now universally popular, despite the fact that the majority of the human species cannot consume them in adulthood without embarassing side effects. See lactose intolerance.
Eggs as dairy?
Most dictionaries define "dairy" in terms of milk products, which would naturally exclude eggs. What's more, the etymology of "dairy" does not seem to have any particular connection to eggs. Nonetheless, popular usage sometimes counts eggs as dairy products; the Open Directory Project, for example, at one point took cooking eggs as a subcategory of cooking dairy products.
Grocery stores in North America often stock eggs very near to "real" dairy products, such that one can often find cartons of eggs sitting under a sign saying "dairy". This could conceivably be either a cause or an effect (or both) of the conception of eggs as dairy products.
