Apple strudel is a traditional Viennese strudel, a popular pastry in Austria, Bavaria, the Czech Republic, Northern Italy, Slovenia, Croatia, and other countries in Europe that once belonged to the Austro-Hungarian Empire (1867–1918).

A strudel is a type of layered pastry with a filling that is usually sweet, but savoury fillings are also common. It became popular in the 18th century throughout the Habsburg Empire. Strudel is part of Austrian cuisine and German cuisine but is also common in other Central European cuisines. In Italy it is recognized as a traditional agri-food product (PAT) of South Tyrol.
