Mary Woodson Jarvis was an American white supremacist, writer, and civic leader who, as the wife of Thomas J. Jarvis, served as the Second Lady of North Carolina from 1877 to 1879 and as the First Lady of North Carolina from 1879 to 1885. She was an active member of the North Carolina Division of the United Daughters of the Confederacy, serving as president of the George B. Singletary Chapter from 1899 to 1916. A promotor of the pseudo-historical Lost Cause of the Confederacy, she authored the book The Ku-Klux Klans, and the booklet The Conditions that Led to the Ku Klux Klans, which glorified the Ku-Klux Klan and condoned the Klan's use of terror against African-Americans in North Carolina.
