A cinnamon roll (also cinnamon bun) is a type of pastry found commonly in North America. It consists of dough onto which cinnamon and sometimes raisins are sprinkled; the dough is then rolled, cut and baked. Cinnamon buns are frequently served with icing of some sort. The size of a cinnamon bun varies from place to place; most vendors supply a smaller size about 5cm in diameter and a larger size about 10cm to a side.

Notable sellers include Cinnzeo in Canada and Cinnabon in the United States.
