Kathryn Magnolia Johnson (December 15, 1878 – November 13, 1954) was an American political activist who began working as a teacher before becoming one of the first members of the National Association for the Advancement of Colored People.
After criticizing the organization's all white leadership roles, Johnson joined the Young Men's Christian Association.
After the organization sent Johnson to France to observe during World War I, Johnson published a book about her findings called, Two Colored Women with the American Expeditionary Forces (1920).
This book was written with Addie Waites Hunton.
The rest of Johnson's life was dedicated to spreading African American activism across the states through book selling to help in the campaign for civil rights.
