Newcomerstown is a village in Tuscarawas County, Ohio, United States, east-northeast of Columbus. In the late 1770s, this was the largest Lenape village on the Tuscarawas River, with 700 residents. Chief Newcomer (Netawatwes) was the leader of the western Lenape here, and they called the village Gekelmukpechunk. Early French traders and English settlers named the village Newcomerstown after the chief. Soon after the start of the American Revolutionary War, the Lenape moved west to Coshocton, about halfway through what is now the next county.
According to some accounts, Newcomerstown was named after an incident that occurred between a Lenape chief and his wife Mary Harris. Chief Eagle Feather grew tired of his wife. He abducted a younger squaw as a second wife and tried to have Harris accept her in her wigwam. Harris allegedly killed Chief Eagle Feather and told the warriors of the village that the young squaw ran away. The warriors hunted the young woman down and killed her. The settlement was thenceforth known as "Newcomerstown", after the squaw.
In 1900, 2,659 people lived in Newcomerstown; in 1910, 2,943. The population was 3,822 at the 2010 census.
