The township was originally named after the Raritan indigenous people. Portions of the township were taken to form Metuchen on March 20, 1900, and Highland Park on March 15, 1905. The name was officially changed to Edison Township on November 10, 1954, in honor of inventor Thomas Edison, who had his main laboratory in the Menlo Park section of the township.
History
Early history

The earliest residents of the area were the Raritan people of the Lenape Native Americans, who lived there and traveled through it to the shore. In 1646, Chief Matouchin led a group of 1,200 warriors.
Edison Township, which was formed from sections of Piscataway and Woodbridge townships, was settled (by Europeans) in the 17th century. The earliest village was Piscatawaytown, which is centered around St. James Church and the Piscatawaytown Common, near the intersection of Plainfield and Woodbridge Avenues in South Edison. The Laing House of Plainfield Plantation (listed on the National Register in 1988), the Benjamin Shotwell House (listed 1987) and the Homestead Farm at Oak Ridge (listed 1995), are buildings from the colonial era included in National Register of Historic Places listings in Middlesex County.
The community was previously known as "Raritan Township", not to be confused with the current-day Raritan Township in Hunterdon County.
The Menlo Park lab was significant in that it was one of the first laboratories to pursue practical, commercial applications of research. It was in his Menlo Park laboratory that Thomas Edison came up with the phonograph and a commercially viable incandescent light bulb filament. Christie Street was the first street in the world to use electric lights for illumination. Edison subsequently left Menlo Park and moved his home and laboratory to West Orange in 1886.
20th century
Near Piscatawaytown village, a portion of the township was informally known as "Nixon", after Lewis Nixon, a manufacturer and community leader. Soon after the outbreak of World War I, Nixon established a massive, volatile-chemical processing facility there, known as the Nixon Nitration Works. It was the site of the 1924 Nixon Nitration Works disaster, a massive explosion and resulting fire that killed 20 people and destroyed several square miles of the township.
In 1954, the township's name was changed to honor inventor Thomas A. Edison. Also on the ballot in 1954 was a failed proposal to change the community's name to Nixon.
In 1959, the Menlo Park Mall, a two-level super regional shopping mall, opened on U.S. Route 1.
