The earliest inhabitants of present-day Ewing Township in the historic era were Lenni Lenape Native Americans, who lived along the banks of the Delaware River. Their pre-colonial subsistence activities in the area included hunting, fishing, pottery-making, and simple farming. Europeans, mostly from the British Isles, began to colonize the area in the 17th and 18th centuries. One of the earliest European settlers was William Green, and his 1717 farmhouse still stands on the campus of The College of New Jersey.

The area that is now Ewing Township was part of Hopewell Township in what was a very large Burlington County at the beginning of the 18th century. In 1714 Hopewell was removed from Burlington County and added to Hunterdon County. By 1719, the area which was to become Ewing Township had been removed from Hopewell Township and added to the newly created Trenton Township. Portions of Trenton Township were incorporated as Ewing Township by an act of the New Jersey Legislature on February 22, 1834, posthumously honoring Charles Ewing for his work as Chief Justice of the New Jersey Supreme Court. The township became part of the newly created Mercer County on February 22, 1838. After incorporation, Ewing Township received additional territory taken from Lawrence Township and the city of Trenton in 1858. In 1894 the city of Trenton took back some of that territory, annexing more in 1900.

When Ewing Township was incorporated in the 19th century, it was primarily farmland with a handful of scattered hamlets, including Carleton (now known as Ewing), Cross Keys (now known as Ewingville), Birmingham (now known as West Trenton) and Greensburg (now known as Wilburtha). Since the beginning of the 20th century, the township has developed as a suburb of Trenton. The sections near the city border are distinctly urban, but most of the township is suburban residential development. The main commercial district extends along North Olden Avenue Extension (County Route 622), originally constructed to connect north Trenton residences with the now-closed General Motors Inland Fisher Guide Plant. Ewing Township today is the location of The College of New Jersey, the Community Blood Council of New Jersey, New Jersey State Police headquarters, the Jones Farm State Correction Institute, the Trenton Psychiatric Hospital, the New Jersey Department of Transportation headquarters, the Katzenbach School for the Deaf and Trenton-Mercer Airport.

From 1953 until 1997 Ewing was the home of Naval Air Warfare Center Trenton, encompassing 528 acres (214 ha) on Parkway Avenue. It was used as a jet engine test facility for the US Navy until its closure based on the recommendations of the 1993 Base Closure and Realignment Commission. Nearly 700 civilian positions were eliminated, most of which were relocated to other facilities in Maryland and Tennessee. The base's Marine operations were transferred to Fort Dix, which has since become Joint Base McGuire-Dix-Lakehurst. A charity to end homelessness acquired the base at no cost in October 2013 in a process involving the United States Department of Defense, the United States Department of Housing and Urban Development, Mercer County and Ewing Township.

The first location of an industrial robot used to replace human workers was at Ewing's Inland Fisher Guide Plant in 1961, a facility that operated in the township for 1938 to 1998, after which the plant was demolished and targeted for redevelopment.


According to the United States Census Bureau, the township has a total area of 15.599 square miles (40.400 km2), including 15.250 square miles (39.497 km2) of land and 0.349 square miles (0.903 km2) of water (2.23%).

The highest elevation in Ewing Township is 225 feet (69 m) AMSL just east of Interstate 95 and just west of Trenton-Mercer Airport, while the lowest point is just below 20 feet (6.1 m) AMSL along the Delaware River near the border with Trenton.

The largest body of water completely within the township is Lake Sylva, a man-made lake that was created in the 1920s when an earthen dam was constructed across the Shabakunk Creek. The 11-acre (4.5 ha) lake is located on the campus of The College of New Jersey. Water courses in Ewing include the Delaware River along its western boundary and the Shabakunk Creek in the eastern and central portions of the township.

Within the township are a number of distinct neighborhoods. These include Agasote, Altura, Arbor Walk, Braeburn Heights, Briarcrest, Briarwood, Cambridge Hall, Churchill Green, Delaware Rise, Ewing, Ewing Park, Ewingville, Fernwood, Ferry Road Manor, Fleetwood Village, Glendale, Green Curve Heights, Hampton Hills, Heath Manor, Hickory Hill Estates, Hillwood Lakes, Hillwood Manor, Mountainview, Parkway Village, Prospect Heights, Prospect Park, Scudders Falls, Shabakunk Hills, Sherbrooke Manor, Somerset, Spring Meadows, Spring Valley, Village on the Green, Weber Park, West Trenton, Whitewood Estates, Wilburtha and Wynnewood Manor. Some of these existed before suburbanization, while others came into existence with the suburban development of the township in the 20th century.
