Alpha-Bits, also known as Frosted Alpha-Bits (styled as AlphA-Bits), was a breakfast cereal made by Post Consumer Brands, which contained frosted alphabet-shaped multi-grain (whole-grain oat and corn flour) cereal bits. Post Cereals also started producing "Marshmallow Alpha-Bits" in 1990.
Alpha-Bits cereal was invented by Thomas M. Quigley who worked for Post Cereals. The cereal was introduced in 1957 and was taken off the market in 2006. However, Alpha-Bits reappeared for sale in January 2008 with a new formulation, touting "0% Sugar!" as a "Limited Edition" cereal. The original recipe was reintroduced later in 2008. The cereal was substantially reformulated in 2017, with the "new and improved" Alpha-Bits having larger shapes than its predecessor. Post Consumer Brands discontinued Alpha-Bits in October 2021. In April 2025, Post announced that due to popular demand, the cereal would return in limited quantities for a limited time in the fall of 2025.
