Poulsbo is a city on Liberty Bay in Kitsap County, Washington, United States. It is the fourth largest city in Kitsap County. The population was 9,200 at the 2010 census.
Founded by Norwegian immigrant Jorgen Eliason in the 1880s, Poulsbo was settled in its early years 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 postmaster, but the authorities in Washington D.C. misspelled the town's name, probably because of illegible handwriting, and the community became known as Poulsbo thereafter. Poulsbo was officially incorporated on December 18, 1907.
