Oyakodon (親子丼), literally "parent-and-child donburi", is a donburi, or Japanese rice bowl dish, in which chicken, egg, sliced scallion (or sometimes regular onions), and other ingredients are all simmered together in a kind of soup that is made with soy sauce and stock, and then served on top of a large bowl of rice. The name of the dish is a poetic reflection of both chicken and egg being used in the dish.
The origins of the dish are unknown. The earliest written mention of the terms "oyako" and "don" in combination is in a newspaper advertisement for a restaurant in Kobe in 1884. The advertisement mentions dishes named oyakojōdon, oyakonamidon and oyakochūdon, possibly referring to different sizes.
Several other Japanese dishes pun on the parent-and-child theme of oyakodon. Tanindon (他人丼), literally "stranger bowl", is otherwise identical but replaces the chicken with beef or pork. A dish of salmon and salmon roe served raw over rice is known as sake oyakodon (鮭親子丼) (salmon parent-child donburi).
