Oreo O's was a breakfast cereal made by Post Foods which consisted of Oreo-flavored O-shaped pieces of cereal. As of 2002 the cereal got a new recipe with real creme filling.  A variation of Oreo O's called Extreme Creme Taste Oreo O's contained Oreo filling flavored marshmallows.
The cereal was launched in 1998 and discontinued in 2007 everywhere outside South Korea. The cereal is no longer available outside of South Korea. As of 2014 Oreo O's have been discontinued by Post and Kraft making the cereal no longer manufactured.
Although unavailable for purchase in the United States, for a time Oreo O's were still produced and available in South Korea, with boxes of this product being available for international purchase on eBay. Korean food manufacturer Dongsuh Foods was established as a joint venture of General Foods and Dongsuh Companies Inc., and was licensed to produce Post Foods cereals in Korea. When Kraft Foods acquired General Foods, half of Dongsuh Foods' stock automatically became property of Kraft, thus making Dongsuh Foods the only company with both licenses required to make Post Foods and Oreo O's. However, since the product was recalled in 2014 due to Dongsuh having intentionally diluted E. coli-contaminated product with normal product, there is no longer any known manufacturer of Oreo O's.
Several advertisements were run on television for Oreo O's. The variation Extreme Crème Oreo O's had its own television commercial that displayed marshmallows with a humanoid shape, dancing around. The advertisement promoted the Extreme Crème Oreo O's variation as more chocolatey in taste, and more creamy.
