United States Congressional Delegations From Colorado
Since Colorado became a U.S.
state in 1876, it has sent congressional delegations to the United States Senate and United States House of Representatives. Each state elects two senators to serve for six years, and members of the House to two-year terms. Before becoming a state, the Colorado Territory elected a non-voting delegate at-large to Congress from 1861 to 1876.
These are tables of congressional delegations from Colorado to the United States Senate and the United States House of Representatives.

Colorado's current congressional delegation to the 118th Congress consists of two senators, both of whom are Democrats, and eight representatives comprising five Democrats and three Republicans.
