Scott McCallum Republican Jim Doyle Democratic The 2002 Wisconsin gubernatorial election was held on November 5, 2002.

McCallum won his party's nomination by defeating two minor candidates, while State Attorney General Jim Doyle won the Democratic primary with a little more than a third of the vote in a highly competitive primary election.

In the general election, the presence of Ed Thompson, former Governor Tommy Thompson's younger brother, the Mayor of Tomah, and the Libertarian Party nominee, held both McCallum and Doyle to under fifty percent of the vote, enabling Doyle to win with 45% of the vote, defeating McCallum.

As of 2022, this is the last gubernatorial election in which the Democratic candidate carried Langlade, Manitowoc, Marquette, Racine, and Taylor counties, and the last in which Juneau County did not vote for the Republican candidate, instead voting for Thompson.

The primary election for the Democratic nomination was closely contested by three competitive candidates.
