It has been suggested that United States House of Representatives elections in Wyoming Territory be merged into this article. (Discuss) Proposed since January 2025.

Wyoming Territory's at-large congressional district is an obsolete congressional district that encompassed the area of the Wyoming Territory. After Wyoming's admission to the Union as the 44th state by act of Congress on July 10, 1890, this district was dissolved and replaced by Wyoming's at-large congressional district.

On July 25, 1868, an act of Congress gave Wyoming Territory the authority to elect a Congressional delegate, although the first delegate did not take his seat until 1869.^[1][2]
