Byram Township was created by an act by the New Jersey General Assembly on February 5, 1798, from portions of the now-defunct Newton Township, and was incorporated on February 21, 1798, as one of New Jersey's initial group of 104 townships. The township was named for the Byram family, who were early settlers in the area. Patriarch Jephthah Byram and his family, were believed to have emigrated to the area after the American Revolutionary War. Before being named Byram, the community had been called Lockwood, and the Lockwood Tavern continued to hold this original name until its demolition in 2015. In 1829, a section of Green Township was incorporated into the township. Portions of the township have been taken to form Sparta township (April 14, 1845), Brooklyn borough (March 24, 1898, now called Hopatcong) and Stanhope borough (March 24, 1904).
