A congressional caucus is a group of members of the United States Congress that meets to pursue common legislative objectives. Formally, caucuses are formed as Congressional Member Organizations (CMOs) through the United States House of Representatives and governed under the rules of that chamber. Caucuses are informal in the Senate, and unlike their House counterparts, Senate groups receive neither official recognition nor funding from the chamber. In addition to the term caucus, they are sometimes called coalitions, study groups, task forces, or working groups.[1]

This is a list of congressional CMOs of the United States Congress, as listed by the House Administration Committee as of October 26, 2018.[2] This article also contains a list of sponsoring Members for Congressional Staff Organizations (CSOs) as of September 24, 2018.[3]
