The 1892 Cincinnati Reds season was a season in American baseball. The National League expanded to 12 teams in 1892, and it was announced that the season would be split into two halves, with the winner of each half meeting each other in a "World's Championship Series". The team finished with a combined record of 82-68, fifth-best in the National League, finishing in fourth place in the first half and in eighth place in the second half.
The Reds acquired outfielder Tip O'Neill during the off-season, as he spent the 1891 season with Comiskey with the Browns, hitting .323 with ten homers and 95 RBI for the club. O'Neill's best season was in 1887 with the Browns, when he hit .435, with 225 hits, 167 runs, 52 doubles, nineteen triples, fourteen home runs and 123 RBI, all which led the American Association. Catcher Morgan Murphy was picked by from the Boston Reds of the AA. Murphy hit .216 with four homers and 54 RBI in 106 games. Another catcher, Farmer Vaughn, was signed after he split the 1891 season between the Cincinnati Kelly's Killers and Milwaukee Brewers of the AA. Vaughn hit .285 with a homer and 23 RBI between the two clubs.
