The township is one of six municipalities in New Jersey under the name Washington (one of which is a borough, five of which are townships). Washington Township, Warren County completely surrounds the borough of Washington. Mansfield Township, also in Warren County, borders both this municipality and another Washington Township in Morris County.
Washington Township was incorporated as a township by an act of the New Jersey Legislature on April 9, 1849, from portions of Mansfield Township. Portions of the township were taken on February 20, 1868, to create Washington Borough.[21] The township was named for George Washington, one of more than ten communities statewide named for the first president.[22][23] It is one of five municipalities in the state of New Jersey with the name "Washington Township".[24] Another municipality, Washington Borough, is completely surrounded by Washington Township.

"First in war, first in peace and, come tomorrow, first in the hearts of his countrymen, George Washington may be nowhere more fondly remembered than in New Jersey, where 12 communities are named for him. The profusion of such names - six Washington Townships, one each in Bergen, Burlington, Gloucester, Mercer, Morris and Warren Counties; Washington in Warren, Washington Crossing in Mercer, Washington Heights and Washington Park in Middlesex, Washingtonville in Sussex and Washington Valley in Morris - causes problems."

"In New Jersey, Washington can lay claim to another first. He's number one in names selected for the state's 566 municipalities. Bergen, Burlington, Gloucester, Morris and Warren counties all have a Washington Township. Warren also has a Washington Borough surrounded—naturally—by Washington Township. The largest is Gloucester County's Washington, with 52,096 people; the smallest is the Washington in Burlington, with a population of 649. New Jersey had a sixth Washington Township in Mercer County until 2008, when voters there approved a name change to Robbinsville."
