United States congressional delegations from Idaho

Since Idaho became a U.S. state in 1890, 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 Idaho Territory elected a non-voting delegate at-large to Congress from 1864 to 1890.

These are tables of congressional delegations from Idaho to the United States Senate and the United States House of Representatives.
