United States congressional delegations from Wyoming

Map showing the location of Wyoming within the United States.

Wyoming has sent congressional delegations to the United States Senate and United States House of Representatives since it became a state in 1890.<ref name="Wyoming-history">Template:Cite book</ref>Template:Rp Before becoming a state, the Wyoming Territory elected a non-voting delegate at-large to Congress, beginning with the 41st United States Congress in 1869.<ref name="congress-delegations">Template:Cite book</ref>Template:Rp Wyoming first sent a voting representative to Congress in the 51st United States Congress, following its statehood.<ref name="congress-delegations" />Template:Rp

Each U.S. 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, Wyoming senators were elected by the Wyoming State Legislature; afterwards, senators were elected directly by the people of the state.<ref name="nara-17th-amendment">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Currently, Wyoming is represented in the Senate by John Barrasso and Cynthia Lummis.<ref name="WY-senators" />

Each state elects at least one member to the House of Representatives for a two-year term. The number of House members is proportional to the state's share of the national population, and changes every ten years with the results of the United States Census.<ref name="const-12">Template:Cite constitution</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Wyoming has had one representative in the House since its statehood.<ref name="congress-delegations" />Template:Rp Currently, Wyoming is represented in the House by Harriet Hageman.<ref name="current-representatives" />

Wyoming's congressional delegations have been exclusively composed of Republicans since the 96th United States Congress in 1979. The last Democrat to represent Wyoming in Congress was Teno Roncalio, who resigned in 1978 when he retired from the House of Representatives.<ref name="Roncalio-bio">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

The Cook Partisan Voting Index (CPVI) is a measure of how strongly partisan a state is.<ref name="cpvi">Template:Cite journal</ref>Template:Rp For each district or state, the CPVI measures the party leaning (Democratic or Republican) and the number of percentage points more partisan than the national average. For instance, a rating of R+4 would mean the district or state voted four percentage points more Republican than the national average, while a rating of D+9 would mean the district or state voted nine points more Democratic than the national average.<ref name="cpvi-about">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> As of 2025, the CPVI rated Wyoming as leaning Republican at R+23.<ref name="2025-CPVI">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
