Lángos (Hungarian pronunciation: [ˈlaːŋɡoʃ]) is a Hungarian food speciality, a deep fried flat bread made of a dough with flour, yeast, salt and water.

Lángos can be made with yoghurt, sour cream or milk instead of water, a dash of sugar along with salt and sometimes with flour and boiled mashed potatoes, which is called Potato Lángos (in Hungarian Krumplis lángos or Krumplislángos). It is eaten fresh and warm, topped with sour cream and grated cheese, or Liptauer, ham, or sausages, rubbed with garlic or garlic butter, or doused with garlic water. Other ingredients and accompaniments can be mushroom, quark cheese, eggplant, cabbage, kefir, omelet, a confectioners' sugar, or jam.

Lángos may be cooked at home or bought from street vendors.

Traditionally lángos was baked in the front of the brick oven, close to the flames. It was made from bread dough and was served as breakfast on the days when new bread was baked. Now that people no longer have brick ovens and do not bake bread at home, lángos is virtually always fried in oil.
