The Rochester Broncos were a short-lived baseball team in the American Association, playing only one season, 1890. They finished fifth in the league with a record of 63-63. Their home games were played at Culver Field.
Rochester was one of three clubs (the other two were Syracuse and Toledo) who played in the International Association in 1889 and were brought in to replace Brooklyn and Cincinnati (who defected to the National League), Baltimore (who left for the Atlantic Association), and Kansas City (who ended up in the Western Association). In the IA, they had played as the Rochester Jingoes.
The Broncos were managed by Pat Powers, who later managed the New York Giants in 1892. Their leading hitter was center fielder Sandy Griffin, who batted .307 in 107 games. Bob Barr (28-24, 3.25) and Will Calihan (18-15, 3.28) were their best pitchers. Cannonball Titcomb threw a no-hitter on Sept. 15.
In 1891, the Broncos played in the Eastern Association as the Rochester Hop Bitters.
