Maryland's at-large congressional district

After the 1960 census, Maryland was apportioned an eighth representative, an increase of one over its 1950 to 1960 apportionment. From 1963 to 1967, the state kept the seven districts it had used since 1953 and used an at-large representative. After 1967, however, eight districts were drawn and the at-large district was eliminated.

Democrat Carlton R. Sickles was the sole at-large representative.
