Emma Guy Cromwell (September 28, 1865 – July 19, 1952) was a suffragist, women's rights activist, and early female Democratic Party politician from Kentucky in the United States.

The Republicans had nominated Eleanor Wickliffe of Bardstown, and both Cromwell and Mary Elliott Flanery stood for the Democratic Party against three male candidates.

[2] Cromwell discovered the records of previous administrations in the Capitol basement, and retrieved and categorized them.

[3] In 1937 Governor Happy Chandler named her State Librarian and Director of Archives, a post she then held for several more terms.

[3] In 1939, Cromwell published her autobiography, Woman in Politics[7] which was republished in 1996 by The Kentucky Commission on Women.

[8] In this book, she praises the suffragist Laura Clay as "my main tutor and adviser (65)" though there is not much detail in her memoir about any work she did for the Kentucky suffrage movement.

Cromwell continued to be active in Democratic Party politics until she fell and broke a hip in 1949.
