Poulsbo (/ˈpɔːlzboʊ/ US dict: pôlz′·bō) 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.

Prior to the arrival of Scandinavian immigrants in the 1880s, the Suquamish people had names for several areas in what is now Poulsbo; one of those names, tcu tcu lats, means place of the maples. Their ancestors occupied villages on the Liberty Bay shoreline — among them, ho-cheeb — for at least 5,000 years, hunted in local forests and floodplains, fished in bays and streams here, and harvested shellfish along the marine shoreline.
