An oliebol (Dutch pronunciation: ['o:libo:]) is a traditional Dutch food. Oliebollen (literally oil balls) are traditionally eaten on New Year's Eve and at funfairs. In wintertime, they are also sold in the street at mobile stalls.

Oliebollen are a variety of dumpling made by using two spoons to scoop a certain amount of dough and dropping the dough into a deep fryer filled with hot oil. In this way, a sphere-shaped oliebol emerges.

The dough is made from flour, eggs, yeast, some salt, milk, baking powder and usually sultanas, currants, raisins and sometimes zest or succade.

They are said to have been first eaten by Germanic tribes in the Netherlands during the Yule, the period between December 26 and January 6. The Germanic goddess Perchta, together with evil spirits, would fly through the mid-winter sky. To appease these spirits, food was offered, much of which contained deep-fried dough.
