Hat Yai is a traditional chicken dish originating from Thailand, also known as Southern Thai fried chicken. The origins of the dish are in the Hat Yai city in southern Thailand, hence the name. In order to prepare it, bone-in, skin-on chicken is marinated in a combination of garlic, soy sauce, oyster sauce, sugar, salt, white and black pepper, and coriander.

The chicken is dipped in batter and fried in hot oil until golden brown. It is then topped with crispy fried shallots and served, usually with rice or a dipping sauce such as nam chim kai (sweet chili sauce) on the side.
