A latke is a type of potato pancake or fritter in Ashkenazi Jewish cuisine that is traditionally prepared to celebrate Hanukkah. Latkes can be made with ingredients other than potatoes such as cheese, onion, carrot, and zucchini.

Potato pancakes are shallow-fried pancakes of grated or ground potato, matzo meal or flour and a binding ingredient such as egg or applesauce, often flavored with grated garlic or onion and seasonings. They may be topped with a variety of condiments, ranging from the savory, to the sweet, or they may be served plain. The dish is sometimes made from mashed potatoes to make pancake-shaped croquettes. Some variations are made with sweet potatoes.
