John West Canned Tuna in Olive Oil

John West is a historic brand specializing in preserved seafood, founded in 1857 by the eponymous T.K. John West in Scotland. Originally a salmon canning pioneer in the United Kingdom and North America, it has evolved into a global seafood leader.

Manufacturing for John West products involves sourcing from various sustainable fishing grounds worldwide, with major production facilities located in Southeast Asia (such as Thailand) and Africa (the Seychelles or Ghana), depending on the specific fish species.

Starting in 2010, the brand was acquired by Thai Union Group based in Thailand. Thai Union is one of the world's largest seafood producers and remains the ultimate owner company as of 2026. The brand is distributed across Europe, the Middle East, and Oceania by various regional subsidiaries.
