Mary Cordelia Montgomery Booze (March 1878 – May 17, 1955) was an American political organizer and activist.

In 1924, Booze became a member of the Republican National Committee; she was one of the first African-American women to do so along with Mary Miller Williams of Georgia.

[3] She became a subject of innuendo in fierce state politics during the 1928 presidential campaign that year.

[4][clarification needed] On August 10, 1927, Mary and her husband, Eugene P. Booze were arrested and charged with the murder of her father, Isaiah Montgomery.

When the couple was charged, it was believed Montgomery had been murdered by poisoning, although at the time of his death it was thought his passing was due to natural causes.
