The herring market or herring fair (Finnish: silakkamarkkinat, Swedish: strömmingsmarknad) is an annual event held in Helsinki, Finland, in October every year. During the herring market, many archipelagans arrive in the Eteläsatama (Södra hamnen) harbour to sell fish and other archipelago products directly from their boats. The event is organised by the city of Helsinki.
The event is very old; according to common knowledge it was first held in 1743. In 1820 its place was settled as Eteläsatama.
The event has been forgotten from time to time, for various reasons, but in the 1980s it was revived and has become very popular.
