Okonomiyaki (お好み焼き, o-konomi-yaki^?) is a Japanese savoury pancake containing a variety of ingredients. The name is derived from the word okonomi, meaning "what you like" or "what you want", and yaki meaning "grilled" or "cooked" (cf. yakitori and yakisoba). Okonomiyaki is mainly associated with Kansai or Hiroshima areas of Japan, but is widely available throughout the country. Toppings and batters tend to vary according to region. Tokyo okonomiyaki is usually smaller than a Hiroshima or Kansai okonomiyaki.

Kansai- or Osaka-style okonomiyaki is the predominant version of the dish, found throughout most of Japan. The batter is made of flour, grated nagaimo (a type of yam), water or dashi, eggs and shredded cabbage, and usually contains other ingredients such as green onion, meat (generally pork or bacon), octopus, squid, shrimp, vegetables, kimchi, mochi or cheese. Okonomiyaki is sometimes compared to an omelette or a pancake and may be referred to as "a Japanese pancake" or even "Osaka soul food".
