The Samuel Gridley and Julia Ward Howe House is a historic rowhouse at 13 Chestnut Street in the Beacon Hill neighborhood of Boston, Massachusetts, United States.

They are now accepted to have been designed by the noteworthy architect Charles Bulfinch, although documentary evidence supporting this notion is lacking, and the attribution has been attended with controversy.

The two were influential forces in the social reform movements of the mid-to-late 19th century, working to advance the causes of the abolition of slavery, including actively heading the Boston Vigilance Committee, which assisted fugitive slaves in the 1850s.

Julia Ward Howe became nationally famous after writing "The Battle Hymn of the Republic" while visiting Washington, D. C. not long after moving into this house.

[2] The Howes lived for many years after their marriage at "Green Peace", a house which no longer stands, in South Boston.
