Summer Lynn Lee (born November 26, 1987) is an American politician and social activist serving as the U.S. representative for Pennsylvania's 12th congressional district since 2023. She is a member of the Democratic Party. Her district encompasses the majority of Pittsburgh and the eastern suburbs, including parts of Westmoreland County. After winning the 2022 congressional primary and the general election, Lee became the first Black woman to represent Pennsylvania in Congress.

Lee was a Democratic member of the Pennsylvania House of Representatives for the 34th district from 2019 to 2022. As of 2025, she is the first black woman to represent Southwestern Pennsylvania in the state legislature. Lee is a former member of the Democratic Socialists of America (DSA). The group supported her in her initial run for state office, but she departed after disagreements with the organization's Pittsburgh chapter. She is considered a member of "The Squad", a small group of young left-leaning Democrats in the U.S. House of Representatives.
