Louis John Barletta (born January 28, 1956) is an American businessman and politician who served as the U.S. representative for Pennsylvania's 11th congressional district from 2011 to 2019. A member of the Republican Party, he served as mayor of Hazleton, Pennsylvania, from 2000 to 2010. As mayor, he came to prominence due to a high-profile immigration ordinance. During his tenure, he challenged longtime Democratic incumbent Paul Kanjorski of the 11th congressional district three times, eventually defeating him in 2010. Barletta was re-elected three times to serve in Congress. In 2018, Barletta was the unsuccessful Republican nominee for the U.S. Senate, losing to Democratic incumbent Bob Casey Jr. by a 13-point margin. He also ran unsuccessfully in the 2022 Republican primary for governor of Pennsylvania, losing to Doug Mastriano.
