Reese's Pieces are a peanut butter candy manufactured by The Hershey Company for the North American market; they are also available in Ireland and the United Kingdom. They are circular in shape and covered in candy shells that are colored yellow, orange, or brown. They can be purchased in plastic packets, cardboard boxes, or cup-shaped travel containers.

Reese's Pieces are a product extension of the Reese's Peanut Butter Cups line; this new product was designed to capitalize on the success of the chocolate-covered peanut butter cups.
