Chicken of the Sea is a provider of packaged seafood, formerly US-owned and now owned by the Thai Union Group of in Samut Sakhon, Thailand. The brand sells tuna, salmon, clams, crab, shrimp, mackerel, oysters, kipper snacks and sardines in cans, pouches, and cups, under the brand names "Chicken of the Sea", "Van Camps", "Genova", "Pacific Pearl", and "Ace of Diamonds".

As a subsidiary, its divisional headquarters is in San Diego, California. The company was founded in 1914 when Frank Van Camp and his son bought the California Tuna Canning Company and changed its name to the Van Camp Seafood Company. The phrase "Chicken of the Sea", first devised as a way to describe the taste, was so successful that soon it also became the company name.

The company's official explanation for the name of their product: In the "old days", fishermen referred to white albacore tuna as "chicken of the sea". It was called this because the white color of its flesh and mild flavor reminded them of chicken. The founder of the company thought this would be a unique name for a brand of tuna, and the Chicken of the Sea brand is now widely known in the Americas.
