The 1849 United States Senate election in Wisconsin was held in the 2nd Wisconsin Legislature on January 17, 1849. Incumbent Democratic U.S. senator Isaac P. Walker was re-elected to a full six-year term.[1]
In the 1849 legislative session, Democrats held a majority in both chambers, but their majority was more tenuous due to the recent schism with the Free Soil Party. The schism, however, removed much controversy from the Democratic nominating process. At the election, the Democrats largely held together and managed to re-elect their nominee.
