The John Johnson House (also known as the Johnson House) is a National Historic Landmark in the Germantown section of Philadelphia, significant for its role in the antislavery movement and the Underground Railroad.

Jennett Rowland Johnson, her children Rowland, Israel, Ellwood, Sarah, and Elizabeth Johnson, and their spouses were members of abolitionist groups such as the American Anti-Slavery Society and the Germantown Freedman's Aid Association.

Through their associations with these groups, the brothers and sisters became involved in the Underground Railroad and used their home, along with the nearby homes of relatives, to harbor fugitive slaves on their journeys to freedom.

[3] The house, then one of the largest in Germantown (then a suburb of Philadelphia), was built between 1765 and 1768 by Jacob Norr for Dirck Jansen, who owned the ground on which nearby Upsala was built.

Jansen had it built for his son John Johnson, Sr. During the 1777 Battle of Germantown, fighting occurred nearby and the house still bears marks of musket balls and cannonballs.
