East Hanover Township is a township in Morris County, New Jersey, United States. As of the 2010 United States Census, the township’s population was 11,157, reflecting a decline of 236 (-2.1%) from the 11,393 counted in the 2000 Census, which had in turn increased by 1,467 (+14.8%) from the 9,926 counted in the 1990 Census. The North America headquarters of Mondelēz International (parent company of Nabisco) and the pharmaceutical company Novartis are located in East Hanover.

The name “Hanover” was adopted by the Township of Hanover on December 7, 1720, in honor of the British King George I of the German dynastic House of Hanover. The boundaries of East Hanover are defined by the joining of two rivers, the Whippany River to the west and north and the Passaic River to the east and north. This geographic effect led to the early name of East Hanover, “Hanover Neck.” Since the creation of Hanover Township in 1720, its size has been considerably decreased as the population of the area has increased. Originally encompassing large portions of Morris County and parts of both Sussex and Warren County, Hanover Township became too unwieldy for a single local government and municipalities split off from the township over time.

East Hanover was incorporated as a township by an act of the New Jersey Legislature on March 12, 1928, from portions of Hanover Township, based on the results of a referendum held on May 9, 1928, that split off both East Hanover Township and Parsippany-Troy Hills from Hanover Township.

According to the United States Census Bureau, the township has a total area of 8.136 square miles (21.074 km²), including 7.892 square miles (20.441 km²) of land and 0.244 square miles (0.633 km²) of water (3.00%).
