Bầu cử thống đốc California năm 1861

The 1861 California gubernatorial election took place on September 4, 1861. Incumbent Governor John G. Downey was not a candidate for renomination, as his Democratic Party had violently ruptured over the issue of slavery and secession. Downey was a Lecompton Democrat, those who favored slavery in the Kansas Territory and who were running as now as the Breckenridge or "Chivalry" Democrats. These Chivalry Democrats supported Attorney General John McConnell. Anti-slavery or anti-secession Democrats were the "Unionist" Democrats who favored John Conness.

With the dire split in the Democratic Party, even more bitter than in 1859, former Republican nominee Leland Stanford won a plurality of the popular vote and became the first Republican governor of California. Both Stanford and Conness later served in the United States Senate.
