Brunswick County is the southernmost county in the U.S. state of North Carolina. As of the 2010 census, the population was 107,431. As its population was only 73,143 in 2000, that makes it one of the fastest growing counties in the state, at a nominal growth rate of about 47% in ten years, with much of the growth centered in the eastern section of the county, the suburbs of Wilmington such as Leland, Belville and Southport. With a 2019 estimated population of 142,820 the county is the 4th fastest growing in the country. The county seat is Bolivia, which at a population of around 150 people is among the least populous county seats in the state. Brunswick County is included in the Myrtle Beach-Conway-North Myrtle Beach, SC-NC Metropolitan Statistical Area. It was formerly part of the Wilmington, NC Metropolitan Statistical Area. Brunswick County and Wilmington area leaders disputed the change, but unsuccessfully. Much of the economy of the county is built around tourism, with beach communities lying along the south-facing beaches past Cape Fear such as Bald Head Island and Oak Island being popular destinations. Calabash, on the border of South Carolina, is renowned for its friedseafood, with "Calabash-style" restaurants dotting the region. The proximity to EUE/Screen Gems Studios in nearby Wilmington has made Brunswick County a popular filming location for many movies and TV shows.
The principal ground-water-supply sources for Brunswick County are the surficial aquifer for domestic supplies and the Castle Hayne aquifer for municipal supplies.

Brunswick County is a member of the regional Cape Fear Council of Governments. The county lies in the inner coastal plain, most of which was highly pro-secession and part of the Democratic “Solid South”. However, Brunswick County was less fertile than the “Black Belt” and consequently had significant pro-Union and Populist sympathies, with the result that the county frequently backed Republicans at state and local levels even when the state was consistently Democratic apart from Herbert Hoover’s 1928 victory. Only three times since the Civil War – Grover Cleveland in 1888, Alton B. Parker in 1904 and Jimmy Carter in 1980 – has Brunswick County backed a losing Democratic presidential candidate. Carter in that 1980 election remains the last Democrat to win a majority of Brunswick County’s ballots, although Bill Clinton won a plurality in 1992.
