Flies' graveyard and flies' cemetery are nicknames used in various parts of the United Kingdom for sweet pastries filled with currants or raisins, which are jokingly said to resemble dead flies.

In Scotland, they are known as fly cakes, fruit slices, or fruit squares.

In Northern Ireland, they are also referred to as currant squares. In the North East of England, the pastries are fly cakes or fly pie.

In Wales, it is called Cacen Pwdin ("dessert cake").^{[citation needed]}

In New Zealand, it is known as a fruit slice or a fly cemetery.^{[citation needed]}

The mixture is similar to sweet mince pies, which are traditionally eaten at Christmas time in the United Kingdom.^{[citation needed]}

The Garibaldi biscuit, which contains a layer of squashed currants, is commonly known as a "fly sandwich", "squashed fly biscuit", or "dead fly biscuit" in the UK.
