A fish market is a marketplace for selling fish and fish products. It can be dedicated to wholesale trade between fishermen and fish merchants, or to the sale of seafood to individual consumers, or to both. Retail fish markets, a type of wet market, often sell street food as well.

Pike Place Fish Market is an open-air fish market at Pike Place Market in Seattle, Washington, United States, located at the corner of Pike Street and Pike Place. Founded in 1930, it is known for its tradition of fishmongers throwing the fish purchased by customers prior to wrapping it. The fish market was near to bankruptcy in 1986, but after the introduction of new practices such as the fish throwing, games, and customer performances, it received significant exposure in national media and on television shows. Pike Place Fish Market is today a world-famous tourist destination, attracting up to 10,000 daily visitors.
