Before the Europeans arrived, the territory of coastal New Hampshire was inhabited for several years by the indigenous American Indians belonging to the Abenaki group and other Algonquian-speaking nations. In 1603, the English explorer Martin Pring became the first known European to explore and write about the area. A fishing settlement was built at the mouth of the Piscataqua River in 1623. In 1630, the west bank of the harbor was settled by the European colonists who named their settlement “Strawbery Banke.” The colonial port prospered due to its strategic location, and soon shipbuilding, lumber, and fishing became the region’s major businesses. Portsmouth served as one of the nation's busiest ports and shipbuilding cities. In 1645, many enslaved Africans were brought to the area as laborers. In 1653, the town was incorporated and named “Portsmouth” in honor of Captain John Mason – the colony’s founder, who also served as the captain of the port of Portsmouth in England.

The town of Portsmouth also initially served as the provincial capital of New Hampshire. Under threats during the American Revolution, the government decided to shift the capital from Portsmouth to the town of Exeter that located much inland compared to Portsmouth. During the Revolutionary War, the African Americans helped to defend the town of Portsmouth and New England. The town of Portsmouth was reincorporated as a city in 1849. Established in 1800, the Portsmouth Naval Shipyard in Kittery, Maine, is the oldest continuously operating shipyard of the US Navy that also played a significant role in facilitating the economic growth of the city of Portsmouth. On September 5, 1905, the Portsmouth Naval Shipyard also served as the site of the signing of the “Treaty of Portsmouth” that officially ended the Russo-Japanese War.
