Women in the United States Senate
Updated: 11/6/2025, 12:45:05 AM Wikipedia source
This article covers the history of women in the United States Senate and various milestones achieved by female senators. It includes a list of all women who have served in the Senate, a list of current female senators, and a list of states represented by women in the Senate. The first female U.S. senator, Rebecca Latimer Felton, represented Georgia for a single day in 1922, and the first woman elected to the Senate, Hattie Caraway, was elected from Arkansas in 1932. As of January 2025, 64 women have served in the upper house of the United States Congress, of which 26 (16 Democrats and 10 Republicans) are currently serving (out of 100 possible seats). Nancy Kassebaum (born July 29, 1932) is the oldest living former female member of the Senate at the age of 93.
