Khachapuri is a traditional Georgian dish of cheese-filled bread. The bread is leavened and allowed to rise and is shaped in various ways, usually with cheese in the middle and a crust which is ripped off and used to dip in the cheese. The filling contains cheese (fresh or aged, most commonly, specialized Khachapuri cheese), eggs and other ingredients.

It is very popular in Georgia, both in restaurants and as street food. As a Georgian staple food, the price of making khachapuri is used as a measure of inflation in different Georgian cities by the "khachapuri index," developed by the International School of Economics at Tbilisi State University. It is Georgia's national dish that is inscribed on the list of the Intangible cultural heritage of Georgia. On the behalf and initiative of Gastronomic Association of Georgia, the 27th of February was announced as the National Khachapuri Day, to celebrate Georgia's timeless signature pastry as well as to promote its recognition internationally.

Khachapuri is popular in the post-Soviet states, including Russia, where it is usually a simple puff pastry with cheese filling (the same pastry with meat filling is called "samsa"). Khachapuri is a popular street food in Armenia, where it is widely served in restaurants and school cafeterias. It has become increasingly popular as a brunch food in Israel, where it was brought over by Georgian Jews.
