The 1860 Republican National Convention in Chicago, Illinois, nominated former U.S. Representative Abraham Lincoln for President and Maine Senator Hannibal Hamlin for Vice-President.

Other candidates at the convention included former New York Governor William Seward, Ohio Senator Salmon P. Chase, former Missouri Representative Edward Bates, and Pennsylvania Governor Simon Cameron.

Seward had been the favorite going into the convention, and led on the first ballots. His lead soon melted away to the dark horse Lincoln, who captured the nomination.

Lincoln-Hamlin went on to defeat three other major tickets that year, including Democratic nominee Stephen Douglas.
