Ewing Township was incorporated as a township by an Act of the New Jersey Legislature on February 22, 1834, from portions of Trenton Township, while the area was still part of Hunterdon County. It became part of the newly-created Mercer County on February 22, 1838.
Although Ewing Township was officially established in 1834, the history of the region ranges back thousands of years. The earliest inhabitants of the land area today known as Ewing Township were the Lenni Lenape Native Americans. These migratory people ranged throughout New Jersey along the banks of the Delaware River, and the Township's many creeks provided rich natural resources for hunting, fishing, pottery-making, and simple farming.
When the region was first settled by European colonists around 1699, it was part of Hopewell Township, and continued under that name until the City of Trenton was established in 1719. From 1719 until 1834, the area was named Trenton Township. On February 22, 1834, the name was changed from Trenton Township to Ewing Township in honor of Charles Ewing, who was posthumously honored for his work as Chief Justice of the New Jersey Supreme Court from 1824-1832.
According to the United States Census Bureau, the township has a total area of 15.6 square miles (40.4 km
) of it is water, mostly consisting of the Delaware River. The total area is 1.73% water.
The highest elevation in Ewing Township is AMSL just east of I-95 and just west of Trenton-Mercer Airport, while the lowest point is just below AMSL near the Delaware River.
Ewing Township shares land borders with Hopewell Township, Lawrence Township, and the City of Trenton, all in New Jersey; the Delaware River separates Ewing from Lower Makefield Township and Yardley Borough, both in Pennsylvania.
