List of United States senators from Maryland

This is a list of United States senators from Maryland, which ratified the United States Constitution April 28, 1788, becoming the seventh state to do so.^[1] To provide for continuity of government, the framers divided senators into staggered classes that serve six-year terms, and Maryland's senators are in the first and third classes.^[2] Before the passage of the Seventeenth Amendment to the United States Constitution in 1913, which allowed for direct election of senators, Maryland's senators were chosen by the Maryland General Assembly, which ratified the amendment on April 1, 2010. Until the assembly appointed George L. Wellington of Cumberland in 1897, senators in class 3 were chosen from the Eastern Shore while senators in class 1 were chosen from the remainder of the state. Barbara Mikulski has been Maryland's longest-serving senator (1987–2017).
