List of United States senators from Pennsylvania

Template:Short description Template:Use mdy dates Template:Multiple image Pennsylvania ratified the United States Constitution on December 12, 1787, and elects its U.S. senators to class 1 and class 3. Officeholders are popularly elected, for a six-year term, beginning January 3. Elections are held the first Tuesday after November 1. Before 1914, they were chosen by the Pennsylvania General Assembly; before 1935, their terms began March 4. The state's current U.S. senators are Democrat John Fetterman (since 2023) and Republican Dave McCormick (since 2025), making it one of four states to have a split Senate delegation, along with Maine, Vermont, and Wisconsin. Arlen Specter was Pennsylvania's longest-serving senator (1981–2011).
