Oladyi are small thick pancakes or fritters common in Russian, Ukrainian and Belarusian cuisines. The batter for oladyi is made from wheat or nowadays more rarely buckwheat flour, eggs, milk, salt and sugar with yeast or baking soda. The batter may also be based on kefir, soured milk or yoghurt.

It may contain various additions, such as apple or raisins.

Oladyi are usually served with sour cream, as well as with sweet toppings such as varenye, jam, powidl, honey etc.  Savoury versions may be served with caviar, similarly to blini.

Generally, the term oladyi in Eastern Slavic cuisines may also denote fritters made with other ingredients, e.g. potato pancakes , carrot fritters , bean pancakes , rice pancakes , summer squash fritters etc. Syrniki quark pancakes may also be considered a type of oladyi.
