The 1972 United States Senate election in Illinois took place on November 7, 1972. Incumbent Republican United States Senator Charles H. Percy sought re-election to the United States Senate. Percy was opposed by Democratic nominee Roman Pucinski, a United States Representative from the Northwest Side of Chicago, whom he was able to defeat handily to win a second term. As of 2022, this was the last time a Republican was elected to the U.S. Senate from Illinois during a presidential election year, the last time an Illinois Republican won a Senate election by double digits, and the last time any candidate has swept every county in the state.
