United States congressional delegations from Arkansas

Since Arkansas became a U.S. state in 1836, it has sent congressional delegations to the United States Senate and United States House of Representatives, beginning with the 25th United States Congress in 1837. Before becoming a state, the Arkansas Territory elected a non-voting delegate at-large to Congress, beginning with the 16th United States Congress in 1819. Each state elects two senators to serve for six years in general elections, with their re-election staggered. Prior to the ratification of the Seventeenth Amendment in 1913, senators were elected by the Arkansas General Assembly. Each state elects varying numbers of members of the House, depending on population, to two-year terms.
