The 1990 United States Senate election in Illinois was held on November 6, 1990. Incumbent Democratic U.S. Senator Paul Simon sought re-election to a second term in office. Simon was opposed by Republican nominee Lynn Morley Martin, a U.S. Congresswoman from Illinois's 16th congressional district, whom he easily defeated to win a second and final term in the Senate.

Primaries were held March 20, 1990.^[1]

The primaries and general elections coincided with those for House, as well as those for state offices.

For the primaries, turnout was 23.02%, with 1,384,324 votes cast.^[1] For the general election, turnout was 53.90%, with 3,251,005 votes cast.^[2]

• Paul Simon (D), incumbent United States Senator
• Lynn Morley Martin (R), United States Congresswoman from Illinois's 16th congressional district

At the start of the election, Martin was considered a formidable challenger, but her campaign floundered – in ads, Martin poked fun at Simon's signature bow tie, but the ad campaign, an attempt at humor, was seen by some as petty and mean-spirited. Martin's campaign suffered from poor fundraising as well, being outspent by Simon by a margin of two-to-one. Simon's popularity proved too much to overcome, and he won with 65 percent of the vote, carrying all but two counties in the state; Edwards County in the southeast and McHenry County outside Chicago, in the heart of the district Martin represented for most of the 1980s. In a midterm favorable to Democrats, Martin was further hurt by negative campaign tactics deployed by advisor Roger Ailes, as well as a number of gaffes. Including, referencing downstate voters as "rednecks".^[3] Martin raised the most campaign funds out of any Republican Senate challenger that cycle.^[3]
