 The first woman to act as governor was Carolyn B. Shelton, who served as Acting Governor of Oregon for one weekend – 9 a.m. Saturday, February 27, through 10 a.m. Monday, March 1, 1909. The outgoing governor, George Earle Chamberlain, had been elected to the U.S. Senate and had to leave for Washington, D.C., before his term was over; the incoming governor, Frank W. Benson, had gotten sick and could not assume office early. Chamberlain left Shelton, his secretary, in charge for the weekend. It was another three and a half years before women were allowed to vote in Oregon.
 The first woman to be acting governor to be entrusted with substantial duties while in office was Soledad Chávez de Chacón, who held the powers and duties of Governor of New Mexico for two weeks in 1924 while Governor James F. Hinkle attended the Democratic Convention in New York. Lieutenant Governor José A. Baca had died in May, so Chacón, the Secretary of State, filled the position. Chacón said that she believed that her 1924 elevation was the first time in the United States that a woman had been called on to assume the responsibilities of the governor.
 The first woman to assume office as governor pursuant to a special election was Nellie Tayloe Ross of Wyoming (widow of late Governor William B. Ross, served from January 1923 to October 1924), who was elected on November 4, 1924, and sworn in on January 5, 1925. Wyoming was the first state to provide women's suffrage after New Jersey had abolished it in 1807. Elected on November 3, 1924, general election, and sworn in on January 20, 1925, was Miriam A. Ferguson of Texas, whose husband, Governor James Edward Ferguson, had previously held the office but he had been impeached and removed from office in 1917. The first woman elected governor without being the wife or widow of a past state governor was Ella T. Grasso of Connecticut, elected in 1974 and sworn in on January 8, 1975.
 To date, no woman has ever changed parties during her gubernatorial term or has been elected as a third party member or an independent.
 Alabama, Arizona, Connecticut, and New Mexico are the only states to have elected women as governors from both major parties. Arizona was the first state where a woman followed another woman as governor (they were from different parties). Arizona also has had the most with 5, and is the first state to have 3 women in a row serve as governor.
