Catherine Ann Devereux Edmondston (October 10, 1823 – January 3, 1875) was an American diarist, planter, and slave owner.

[1] She was tutored in literature, mathematics, science, and philosophy before attending Belmont, a Christian school for girls run by Margaret Mercer near Leesburg, Virginia.

Her husband served on the executive committee, and as vice president, of the Scotland Neck Agricultural Society and as an aid to the governor of South Carolina.

[1] Even after the end of the war, Edmondston remained upset about the Confederacy's defeat, publishing a short essay in 1872 about her antagonism towards the North which was titled The Morte d'Arthur.

A devout Episcopalian, she was buried in the cemetery at Trinity Episcopal Church in Scotland Neck, North Carolina.
