County of onslow

north carolina

History & Founding

Located in the coastal plains of eastern North Carolina, this county boasts a rich history and a vibrant community. Established in 1734 from Carteret County, it was named in honor of William Drysdale Onslow, a member of the Colonial Assembly and a prominent figure in the early governance of North Carolina. The original inhabitants were Native American tribes, primarily the Tuscarora, before European settlement. The county played a significant role in the Revolutionary War, serving as a strategic location for both British and American forces. During the Civil War, it provided troops for the Confederate army, and the region experienced considerable disruption. An interesting anecdote from the county’s past involves the legend of the "White Deer of Onslow," a local folktale about a ghostly white deer said to roam the forests, captivating residents for generations.

Geography & Landscape

The county occupies a geographically diverse area within the state’s southeastern corner. Situated along the Intracoastal Waterway and the New River, it benefits from extensive waterways. The terrain is predominantly flat, characteristic of the coastal plains, with gently rolling hills inland. The New River, a blackwater river known for its scenic beauty and recreational opportunities, flows through the county. While mountains are absent, the landscape offers expansive views of the surrounding countryside. The climate is humid subtropical, with warm summers and mild winters. Average annual rainfall is plentiful, contributing to the lush vegetation. Notable natural features include extensive wetlands and diverse wildlife habitats.

Economy & Communities

The county is comprised of nine towns and cities, with Jacksonville serving as the county seat and largest population center. The economy is diverse, historically reliant on agriculture, particularly tobacco, sweet potatoes, and timber. Today, the military plays a dominant role, with Camp Lejeune, a United States Marine Corps base, being the largest single employer and a significant driver of the local economy. Manufacturing, healthcare, and tourism are also important sectors. Smaller towns maintain a more rural character, while Jacksonville and New Bern exhibit more suburban and urban qualities. Notable employers beyond the military include Novant Health and various retail chains. The area’s character is a blend of military presence, coastal charm, and agricultural heritage.
