The Old Manse is an historic manse famous for its American literary associations. It is now owned and operated as a nonprofit museum by the Trustees of Reservations. The house is located on Monument Street in Concord, Massachusetts, and it neighbors the North Bridge over the Concord River, a part of Minute Man National Historical Park.

The Old Manse was built in 1770 by Rev. William Emerson, father of noted minister Rev. William Emerson and grandfather of famous transcendentalist writer and lecturer Ralph Waldo Emerson. The builder was the town minister in Concord, chaplain to the Provincial Congress when it met at Concord in October 1774 and later a chaplain to the Continental Army. Rev. Emerson observed the fight at the North Bridge, a part of the Concord Fight, from his farm fields while his wife and children witnessed the fight from the upstairs windows of their house.

Rev. Emerson died in October 1775 in West Rutland, Vermont, while returning home from Fort Ticonderoga. His widow remarried, to the Rev. Ezra Ripley, and the family continued to live in the Old Manse. Rev. Ripley served as Concord's town minister for 63 years.

Nathaniel Hawthorne (born Nathaniel Hathorne; July 4, 1804 – May 19, 1864) was an American novelist and short story writer.

Nathaniel Hawthorne was born in 1804 in the city of Salem, Massachusetts to Nathaniel Hathorne and the former Elizabeth Clarke Manning. His ancestors include John Hathorne, the only judge involved in the Salem witch trials who never repented of his actions. Nathaniel later added a "w" to make his name "Hawthorne" in order to hide this relation. He entered Bowdoin College in 1821, was elected to Phi Beta Kappa in 1824, and graduated in 1825. Hawthorne anonymously published his first work, a novel titled Fanshawe, in 1828. He published several short stories in various periodicals which he collected in 1837 as Twice-Told Tales. The next year, he became engaged to Sophia Peabody. He worked at a Custom House and joined Brook Farm, a transcendentalist community, before marrying Peabody in 1842. The couple moved to The Old Manse in Concord, Massachusetts, later moving to Salem, the Berkshires, then to The Wayside in Concord. The Scarlet Letter was published in 1850, followed by a succession of other novels. A political appointment took Hawthorne and family to Europe before their return to The Wayside in 1860. Hawthorne died on May 19, 1864, and was survived by his wife and their three children.
