Peter Pan is an American brand of peanut butter that is marketed by Post Consumer Brands, part of Post Holdings. Named after the J. M. Barrie character, the product was introduced by Swift & Company in 1920 under the name "E. K. Pond" and renamed in 1928.

Peanut butter is a food paste or spread made from ground, dry-roasted peanuts. It commonly contains additional ingredients that modify the taste or texture, such as salt, sweeteners, or emulsifiers. Consumed in many countries, it is the most commonly used of the nut butters, a group that also includes cashew butter and almond butter.
