This is a List of United States Senators from Maryland. Maryland ratified the Constitution on April 28, 1788, becoming the seventh state to do so. 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. 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. 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.

Class 1

Class 1 U.S. Senators belong to the electoral cycle that were elected for one session of the U.S. Congress in the first election of 1788 and whose seats in recent years are contested in 1994, 2000, 2006, and 2012.
