Cantonese seafood soup is one of the main seafood soups within Cantonese cuisine. It is commonly found in Hong Kong, and is also available in Chinatowns in other nations. The soup is usually considered midrange to high-end in price, depending on the ingredients.
The soup is generally thick with a very smooth texture, due to the use of starch as a thickening agent. It is usually whitish and a little transparent. The name of the dish describes it as a "gung" () rather than the standard Chinese term for soup (tang, 汤); this reflects its southern Chinese origin.
