The 1865 Wisconsin gubernatorial election was held on November 7, 1865. Republican Party candidate Lucius Fairchild won the election with nearly 55% of the vote, defeating Democratic candidate Harrison Carroll Hobart. The incumbent Governor, James T. Lewis, refused nomination for re-election. The American Civil War had concluded just a few months before this election was held; both major party candidates in this election were retired brigadier generals who had served with distinction in the war.
