Rebecca A. Balint (/ˈbælɪnt/ BAL-int; born May 4, 1968) is an American politician who is a member of the United States House of Representatives from Vermont's at-large congressional district as a member of the Democratic Party. She served as a member of the Vermont Senate from Windham County from 2015 to 2023, as majority leader from 2017 to 2021, and as president pro tempore from 2021 to 2023.

Balint was born in Heidelberg, West Germany, and raised in Peekskill, New York. She was educated at Walter Panas High School, Smith College, Harvard University, and the University of Massachusetts Amherst. She moved to Vermont in 1994, and worked as a teacher, rock-climbing instructor, and columnist for the Brattleboro Reformer, and was active in local politics. Balint was elected to the State Senate in 2014, becoming the first openly acknowledged lesbian to serve there. She was selected to serve as majority leader and later elected president pro tempore, the first woman and openly LGBT person to do so in Vermont.

Balint was elected to the U.S. House in the 2022 election. She is the first woman and openly LGBT person to represent Vermont in Congress. Prior to her election, Vermont was the only state that had not previously elected a woman to Congress.

Rebecca A. Balint was born at the United States Army hospital in Heidelberg, West Germany, on May 4, 1968, the daughter of Peter and Sandra (Couchman) Balint, and raised in Peekskill, New York. Her grandfather was murdered on a death march from the Mauthausen concentration camp during the Holocaust; her Hungarian-Jewish father immigrated to the U.S. in 1957. She graduated from Walter Panas High School in 1986. In the sixth grade, she admitted to having a crush on a female classmate, for which other students taunted her, including writing "lezzie" on her locker; she came out to her friends after high school and to her parents while she was in college. Balint became interested in politics at an early age, which she later attributed to having been raised in a family affected by the Holocaust and observing how government actions affect women and minorities, including gays and lesbians.

Balint attended Barnard College of Columbia University before transferring to Smith College. She graduated magna cum laude from Smith with a Bachelor of Arts degree in history and women's studies in 1990, received a Master of Education degree from Harvard University in 1995, and completed a Master of Arts degree in history from the University of Massachusetts Amherst in 2000. At Smith College, Balint was coxswain for the women's crew team, who nicknamed her "the Admiral" because of her leadership skills.

Balint moved to Vermont in 1994, and taught middle school history and social studies and worked as a rock-climbing instructor at Farm & Wilderness summer camps in Plymouth, Vermont, in addition to teaching at the Community College of Vermont in Brattleboro and writing a column for the Brattleboro Reformer. She met Elizabeth Wohl in 2000; they formed a civil union in 2004, moved to Brattleboro in 2007, and got married in 2009, after same-sex marriage was legalized in Vermont. They have two children.

Balint supported the Vermont Progressive Party in the 2000s, and supported their gubernatorial nominee, Anthony Pollina, in the 2000 election. She served as a town meeting representative and on the Development Review Board in Brattleboro.

In 2014, Balint announced her campaign for a Vermont Senate seat from the two-member Windham district. She raised the most money in the race, around $13,000, with donations from people such as Jane Lynch, and was endorsed by Majority Leader Philip Baruth. Windham County Democratic Party chair Brandon Batham served as her campaign manager; he later served as a member of the city council in Barre and operations manager for the Vermont Democratic Party before being accused of embezzling party funds.
