Plymouth is a rural town in Grafton County, New Hampshire, United States, in the White Mountains Region. It has a unique role as the economic, medical, commercial, and cultural center for the predominantly rural Plymouth, NH Labor Market Area.^[3] Plymouth is located at the confluence of the Pemigewasset and Baker rivers and sits at the foot of the White Mountains. The town's population was 6,682 at the 2020 census.^[2] It is home to Plymouth State University, Speare Memorial Hospital, and Plymouth Regional High School.

The town's main center, where 4,730 people resided at the 2020 census (three-quarters of whom are college student age),^[4] is defined as the Plymouth census-designated place (CDP), and is located along U.S. Route 3, south of the confluence of the Baker and Pemigewasset rivers.

Plymouth State University, in the center of town, has an undergraduate class size of 4,000 students and a graduate class size of 1,000 students.^{[citation needed]}

Plymouth was originally the site of an Abenaki village that was burned to the ground by Captain Thomas Baker in 1712. This was just one of the many British raids on American Indian settlements during Queen Anne's War. Part of a large plot of undivided land in the Pemigewasset Valley, the town was first named "New Plymouth", after the original Plymouth Colony in Massachusetts. Colonial Governor Benning Wentworth granted Plymouth to settlers from Hollis, all of whom had been soldiers in the French and Indian War. Some had originally come from Plymouth, Massachusetts. The town was incorporated in 1763.^[5] Parts of Hebron and Campton were annexed in 1845 and 1860.

In 1806, then-lawyer Daniel Webster lost his first criminal case at the Plymouth courthouse, which now houses the Historical Society.^[6] The author Nathaniel Hawthorne, while on vacation in 1864 with former U.S. President Franklin Pierce, died in Plymouth at the second Pemigewasset House, which was later destroyed by fire in 1909. In the early 20th century, the Draper and Maynard Sporting Goods Company (D&M) sold products directly to the Boston Red Sox, and players such as Babe Ruth would regularly visit to pick out their equipment. The Plymouth Normal School was founded in 1871 out of the already existing Holmes Plymouth Academy, becoming the state's first teachers' college. It would later evolve into Plymouth Teachers' College in 1939, Plymouth State College in 1963, and finally Plymouth State University in 2003.
