Brandywine Hundred (also known as North Wilmington) is an unincorporated subdivision of New Castle County, Delaware, United States.

However, while their names still appear on all real estate transactions, all other hundreds in Delaware presently have no meaningful use or purpose except as a geographical point of reference.

The town of Bellefonte, the villages of Arden, Ardencroft, and Ardentown, the Claymont and Edgemoor Census Designated Places (CDP), and the community of Talleyville are in Brandywine Hundred.

In recent decades the Hundred has become a major edge city of Philadelphia due in part to Delaware General Corporation Law.

Ebright Azimuth, the highest natural elevation in the state at 448 feet (137 m), is located along the northern edge of Brandywine Hundred, very close to the Pennsylvania line.
