Mills, Janet T. (Janet Trafton), 1947-

Janet Trafton Mills (born December 30, 1947) is an American politician and lawyer serving as the 75th governor of Maine since January 2019. She is a member of the Democratic Party.

A native of Farmington, Maine, Mills briefly attended Colby College before briefly moving to San Francisco where she worked as nursing assistant. She later enrolled at the University of Massachusetts Boston, from which she graduated with a bachelor of arts degree in 1970. In 1973, she began attending the University of Maine School of Law, graduating with a JD in 1976.

Mills was Maine's first female criminal prosecutor and was an assistant attorney general from 1976 to 1980, prosecuting homicides and other major crimes. In 1980, she was elected district attorney for Androscoggin, Franklin and Oxford counties, a position to which she was reelected three times. She was the first woman district attorney in New England. In 1994, Mills was an unsuccessful candidate for the United States Congress in the Democratic primary to replace then-Republican congresswoman Olympia Snowe. She placed 3rd, losing to John Baldacci. In 2002, Mills was elected to the Maine House of Representatives, serving until being elected the 55th Attorney General of Maine, serving in that office from January 6, 2009 to January 6, 2011.

When Republicans gained control of the Maine Legislature in 2010, Mills, a Democrat, was not reelected to another term as Attorney General. In January 2011, she was elected vice chair of the Maine Democratic Party and joined the law firm Preti Flaherty in February 2011. After Democrats regained control of the legislature in the 2012 elections, she was again chosen to be attorney general, resigning as vice chair of the Maine Democratic Party. Her second stint as Attorney General lasted from January 7, 2013 until January 2, 2019. On July 10, 2017, Mills announced that she would seek the Democratic nomination for governor of Maine in 2018. Winning the Democratic nomination after four rounds of ranked-choice voting, she went on to win the general election with 50.9 percent of the vote, the first governor since 1966 to win a majority of the vote for a first term.
