When the region was first settled by a mixture of European and American 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 State Supreme Court from 1824-1832.
Today, Ewing Township holds a diverse community of residents, along with a business economy that is strongly emphasized with local and state government, light manufacturing, and many small businesses. It is conveniently located with easy access to Philadelphia and New York, as well as acting as a corridor for air, rail, and land transportation; including the West Trenton Train Station, The Trenton-Mercer Airport and Interstate 95.
