A lemon tart (French: tarte au citron) is a dessert dish, a variety of tart. It has a pastry shell with a lemon flavored filling.

In the United Kingdom, lemon tart consists of a pastry case (often made in a fluted tart tin) containing a baked lemon custard (usually composed of eggs, sugar, lemon juice and cream). Usually recipes include blind-baking before adding the custard. Sometimes, the tart is dusted with icing sugar prior to serving.^[1][2][3][4]

Alternatively, the lemon filling can be cooked in a saucepan and then added to the baked pastry case.^[5]

A dessert very similar to the lemon tart is the Shaker lemon pie, usually served for dessert, made with a crust usually made of shortcrust pastry and lemon custard filling. The lemon pie is prepared with a bottom pie crust.

Distinct from the Shaker lemon pie is the lemon meringue pie, the latter which has no upper crust but meringue on top instead.
