A Swiss roll or jelly roll is a type of sponge cake roll. The thin cake is made of eggs, flour and sugar and baked in a very shallow rectangular baking tray, called a sheet pan. The cake is removed from the pan and spread with jam or butter cream, rolled up, and served in circular slices.

The origins of the term "Swiss" roll are unclear and the cake originated in Central Europe and not Switzerland. It is a traditional German, Hungarian and probably Austrian type of cake. The shape of the Swiss roll has inspired usage of the term as a descriptive term in other fields, such as in optics.
