Dorothy Quincy Hancock Scott (/ˈkwɪnzi/; May 10, 1747 – February 3, 1830) was an American hostess, the daughter of Justice Edmund Quincy of Braintree and Boston.[1] Her aunt, also named Dorothy Quincy, was the subject of Oliver Wendell Holmes' poem Dorothy Q.[2] She is best known as the wife of John Hancock, signer of the Declaration of Independence.

She was raised at the Quincy Homestead in what is now Quincy, Massachusetts. The house in which she lived has been designated a National Historic Landmark, and is known as the Dorothy Quincy House. She married John Hancock in 1775.

In 1796, Quincy married Captain James Scott (1742–1809), who had been employed by Hancock as a captain in his trading ventures with England. They lived in Portsmouth, New Hampshire, and had no children together. When Captain Scott died, Dorothy moved back into the Hancock Mansion at 30 Beacon Street in Boston for about 10 years. After that time she lived at 4 Federal Street in Boston.

Dorothy was a well known hostess and a great deal was written about her. Many chroniclers of the time note that she was not only beautiful, but well spoken and intelligent. She witnessed the Battle of Lexington while staying with her future husband's aunt, Lydia Hancock, at the home of Rev. Jonas Clark.[3] When Hancock told her after the battle that she could not go back to her father in Boston, she retorted, "Recollect Mr. Hancock, that I am not under your control yet. I shall go to my father tomorrow."
