Wisconsin Territory had a non-voting delegate to the United States House of Representatives.
The district was eliminated with the creation of the Minnesota Territory on March 2, 1849, as Wisconsin was admitted into the union as a state. However, Henry Sibley continued to serve out his term as the Delegate from the Territory of Wisconsin until March 3, 1849, making the district's effective elimination on March 3, 1849, the conclusion of the Congress.
Three congressional districts were established when Wisconsin was granted statehood, and it remains the only U.S. state to never have been represented by an at-large congressional district as a state.
