Hainan cuisine, or Hainanese cuisine, is derived from the cooking styles of the peoples of Hainan Province in China. The food is lighter, less oily, and more mildly seasoned than that of the Chinese mainland. Seafood predominates the menu, as prawn, crab, and freshwater and ocean fish are widely available.

Congee, mantou and baozi are eaten for breakfast, with a noodle dish also being widely eaten. This consists of fine, vermicelli-type noodles with various toppings and gravy. Along with lunch and dinner, late night outdoor barbecue dishes are also served.
