The 2000 United States Senate election in Arizona was held on November 7, 2000. Incumbent Republican U.S. Senator Jon Kyl won re-election to a second term. No candidate was nominated from the Democratic Party. Independent Bill Toel, Green party nominee Vance Hansen, and Libertarian party nominee Barry Hess each got more than 5% of the vote, a strong non-major-party performance.
Jon Kyl, a popular incumbent, did not draw a Democratic opponent despite being labeled as vulnerable at one point.
