United States congressional delegations from Maryland

These are tables of congressional delegations from Maryland in the United States House of Representatives and the United States Senate.

The current dean of the Maryland delegation is Representative and former House Majority Leader Steny Hoyer (MD-5), having served in the House since 1981.

From 1963 through 1967, the eighth seat was elected at-large statewide.

Starting in 1967, however, the state was redistricted and an eighth district was created.

The alternating grey and white boxes indicate the duration of six-year Senate terms.
