The third United States Chess Congress was held in the city of Chicago, Illinois from July 7th to the 16th, 1874. Eight American chess masters and players participated in the "double rounds" master event by paying an entry fee of $20. The participants were previous US Congress winner George Henry Mackenzie, previous US Congress participants Frederic Elder, Henry Hosmer, Max Judd, Hiram Kennicott, and Frederick Perrin, as well as Frederick Bock and James Adams Congdon. The time control was fifteen moves every hour and for the first time in an organized US tournament draws were not required to be replayed. Elder and Kennicott both had to withdraw before their games could be completed, however the games played, their scores, and subsequent standings were included at the final. Games decided by forfeit have been omitted from this collection due to their absence from the database. As with many tournaments and events from the 19th century, no official organization of rounds or scheduling was in place, so the games are organized below according to the days in which play began. Mackenzie won his second consecutive American Chess Congress as well as the $225 grand prize by finishing clear first with +9, yet just half a point of second place Hosmer.
