Lucia Kay McBath (née Holman; born June 1, 1960) is an American politician who has served in the United States House of Representatives from a district in the suburbs of Atlanta, Georgia, since 2019. She represented Georgia's 6th congressional district from 2019 to 2023 and since 2025, and has represented the neighboring 7th district from 2023 to 2025. McBath is a member of the Democratic Party.

McBath's son, Jordan Davis, was murdered in November 2012. She then became an advocate for gun control, joining other mothers of black murder victims to form the Mothers of the Movement, and spoke at the 2016 Democratic National Convention.

McBath ran for the House of Representatives in 2018, narrowly defeating Republican incumbent Karen Handel and defeating her again in 2020. McBath switched to the 7th district after redistricting in 2020 made the 6th significantly more favorable to Republicans; she defeated the 7th's incumbent, Carolyn Bourdeaux, in the Democratic primary and won the general election.
