O ATP de Cincinnati (também conhecido como Cincinnati Open, para fins de patrocínio), é um torneio profissional de tênis masculino disputado em quadra dura no Lindner Family Tennis Center, em Mason, na região metropolitana de Cincinnati, Ohio, nos Estados Unidos. Com primeira edição em 1899, é o mais antigo torneio de tênis norte-americano realizado em sua cidade de origem, e é um dos nove ATP Masters 1000 do circuito ATP da temporada.
Em 2020, devido à pandemia de COVID-19, o torneio ocorrerá excepcionalmente na cidade de Nova York, no mesmo espaço do US Open, na semana anterior ao evento do Grand Slam norte-americano.
