Muriel Elizabeth Bowser (born August 2, 1972) is an American politician who has served as the current mayor of the District of Columbia since 2015. A member of the Democratic Party, she previously represented the 4th ward as a member of the Council of the District of Columbia from 2007 to 2015. She is the second female mayor of the District of Columbia after Sharon Pratt. Since taking office in 2015, she has secured three consecutive mayoral victories—the first African‑American woman to do so.

Elected to the Advisory Neighborhood Commission in 2004, Bowser was elected to the council in a special election in 2007, to succeed Adrian Fenty, who had been elected mayor. She was reelected in 2008 and 2012 and ran for mayor in the 2014 election. She defeated incumbent mayor Vincent C. Gray in the Democratic primary and won the general election against three independent and two minor party candidates with 55% of the vote. In 2018, Bowser won a second term with 76.4% of the vote, then a third term in 2022 with 74.6% of the vote.
