Chesapeake is an independent city in Virginia, United States. At the 2020 census, the population was 249,422, making it the second-most populous city in Virginia, the tenth largest in the Mid-Atlantic, and the 92nd-most populous city in the United States.

Chesapeake is located in the Hampton Roads metropolitan area. One of the cities in the South Hampton Roads, Chesapeake was organized in 1963 by voter referendums approving the political consolidation of the city of South Norfolk with the remnants of the former Norfolk County, which dated to 1691. (Much of the territory of the county had been annexed by other cities.) Chesapeake is the second-largest city by land area in the Commonwealth of Virginia, and the 17th-largest in the United States.

Chesapeake is a very diverse city in which a few urban areas are located; it also has many square miles of protected farmland, forests, and wetlands, including a substantial portion of the Great Dismal Swamp National Wildlife Refuge. Extending from the rural border with North Carolina to the harbor area of Hampton Roads adjacent to the cities of Norfolk, Portsmouth, Suffolk, and Virginia Beach, Chesapeake is located on the Atlantic Intracoastal Waterway. It has miles of waterfront industrial, commercial and residential property. In 2011, Chesapeake was named the 21st best city in the United States by Bloomberg Businessweek. Chesapeake is home to the international headquarters of Dollar Tree.

In 1963, the new independent city of Chesapeake was created when the former independent city of South Norfolk consolidated with Norfolk County. The consolidation was approved, and the new name selected by the voters of each community by referendum and authorized by the Virginia General Assembly.

Formed in 1691 in the Virginia Colony, Norfolk County had originally included essentially all the area which became the towns and later cities of Norfolk, Portsmouth, and South Norfolk. Its area was reduced after 1871 as these cities added territory through annexations. Becoming an independent city was a method for the former county to stabilize borders with neighbors, as cities could not annex territory from each other.

The relatively small city of South Norfolk had become an incorporated town within Norfolk County in 1919 and became an independent city in 1922. Its residents wanted to make a change to put their jurisdiction on a more equal footing in other aspects with the much larger cities of Norfolk and Portsmouth. In addition, by the late 1950s, although immune from annexation by the bigger cities, South Norfolk was close to losing all the county land adjoining it to the city of Norfolk in another annexation suit.

The consolidation that resulted in the city of Chesapeake was part of a wave of changes in the structure of local government in southeastern Virginia which took place between 1952 and 1975.

The Chesapeake region was among the first areas settled in the state's colonial era, when settlement started from the coast. Along Chesapeake's segment of the Intracoastal Waterway, where the Great Bridge locks marks the transition between the Southern Branch Elizabeth River and the Chesapeake and Albemarle Canal, lies the site of the Battle of Great Bridge. Fought on December 9, 1775, in the early days of the American Revolutionary War, the battle resulted in the removal of Lord Dunmore and all vestiges of English Government from the Colony and Dominion of Virginia.
