Sugar pie is a dessert in northern French and Belgian cuisine, where it is called tarte au sucre. It is also popular in Canada.

Various type of tarte au sucre are made. Some are a leavened dough topped with beet sugar or brown sugar, others have a crust containing a homogeneous sugar mixture which is similar to caramel after baking. The French Canadian version of the dessert sometimes uses maple syrup.

In Canada, the sugar pie is considered a classic dish of Québécois cuisine. In 2019, the sugar pie was featured on a Canadian postage stamp.
