Ritter Sport is a brand of chocolate from Alfred Ritter GmbH & Co. KG, headquartered in Waldenbuch, Germany.

Each 100 gram square-shaped bar is divided into 16 smaller squares, creating a four-by-four pattern. In 2013 the company introduced a new version that is divided into 9 smaller squares using a three-by-three pattern. Large bars weighing 250 grams and 16.5 gram mini bars are also available, although in fewer varieties.
