Horace White Wilkie (January 9, 1917 – May 23, 1976) was an American attorney, judge, and Democratic politician from the U.S. state of Wisconsin.

During World War II, Wilkie served in the United States Coast Guard.

After the war, he helped revive the Democratic Party of Wisconsin with other young liberals and former members of the Wisconsin Progressive Party in what was known as the Democratic Organizing Committee.

[1] An odd coincidence of Justice Wilkie's career is that his successors in the Wisconsin State Senate and Wisconsin Supreme Court both became the longest-serving members of those respective bodies.

[5] Shirley Abrahamson, who succeeded him on the Wisconsin Supreme Court, served from 1976 through 2019.
