Portsmouth, Pacifica is a suburban city in the Quad-Cities Metro Area in Pacifica. The city has a population of 85,540 as of the 2010 census and is the wealthiest incorporated city in Pacifica on the affluence index.

Portsmouth is bordered by Wamash to the west, Sahalee to the north, Sumner to the east, and the state of Washington to the south and southeast, as well as Semiahmoo Bay to the southwest. Portsmouth is located in Nansett County.

The city originally was a port on Semiahmoo Bay that started as a fishing village founded by transplants left in the Fraser Territory after the Alaskan War and was a notoriously violent town populated by prospectors in the Fraser Gold Rush in the 1890's and early 1900's. With the growth of the Quad-Cities, Portsmouth evolved initially into a blue-collar town with farmland within its city limits thanks to expansions in 1923 and 1940. It eventually evolved into an affluent suburb thanks to immigration in the 1950's and 60's and due to the growth of professionalized work in the Quad-Cities area and its prime beachfront location that was unmarred by major shipping, like the kind that powered Wamash or nearby Bellingham. The town underwent several radical remodels and redesigns in the 1970's and 1990's to better establish a "waterfront" and enjoyed a healthy real estate boom beginning in the late 1980's.
