Janet Trafton Mills (born December 30, 1947) is an American politician and lawyer serving since 2019 as the 75th governor of Maine. She served four nonconsecutive two-year terms as Maine Attorney General, from 2009 to 2011 and from 2013 to 2019.

A member of the Democratic Party, Mills was first elected attorney general by the Maine Legislature on January 6, 2009, succeeding G. Steven Rowe. Her second term began on January 3, 2013, after the term of William Schneider. She was the first woman to hold the position. Before her election, she served in the Maine House of Representatives, representing the towns of Farmington and Industry. Her party nominated her for governor in the 2018 election, and she won, defeating Republican Shawn Moody and independent Terry Hayes. On January 2, 2019, she became Maine's first female governor. Mills was reelected in 2022.

On October 14, 2025, Mills launched her campaign in the 2026 United States Senate election in Maine, seeking the Democratic nomination to face five-term incumbent Republican Susan Collins.
