This is a list of breakfast cereals. Many cereals are trademarked brands of large companies, such as Kellogg's, General Mills, Malt-O-Meal, Nestlé, Quaker Oats and Post Foods, but similar equivalent products are often sold by other manufacturers and as store brands.(This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.)
