Poulsbo has a long history as a destination for immigrants from Scandinavia, particularly Norway and Finland. Downtown Poulsbo maintains a Scandinavian theme in its shops and restaurants, and is a popular regional tourist destination. One of its local products is now available worldwide, Poulsbo Bread, originally made in the local bakery. Many visitors arrive by boat; there are three marinas near the town, and the town's harbor is an excellent anchorage.
Founded by Norwegian immigrant Jorgen Eliason in the 1880s, Poulsbo was originally settled by a large number of Norwegian and other Scandinavian immigrants because of its similarities to their native countries. In 1886 I. B. Moe, one of the early Norwegian settlers, suggested that the community should have a post office. Moe suggested the town be named Paulsbo (which translates as "Paul's place"), after the Norwegian village where Moe spent his early years. The community's petition for a post office was granted, and Moe became the first Post Master General, but the authorities in Washington D.C. misspelled the town's name, due to illegible handwriting on the part of the post master, and the community became known as Poulsbo thereafter. Poulsbo was officially incorporated on December 18, 1907.
Poulsbo, up until World War II, had retained Norwegian as its primary language. However, during World War II, the military constructed about 300 residential units to provide housing for workers at the nearby Puget Sound Naval Shipyard, located in Bremerton, Washington. The population of Poulsbo almost tripled over three years, and the diversification of the population led to the dominance of English as the primary language.
