El Masters de Cincinnati, conegut oficialment com a Western & Southern Open, és un torneig de tennis professional que es disputa anualment sobre pista dura al Lindner Family Tennis Center de Cincinnati, Ohio, Estats Units. Pertany a les sèries Masters 1000 del circuit ATP masculí i als Premier Tournaments (Premier 5) del circuit WTA femení.
Història Anteriorment es disputaven per separat les categories masculines i femenines, tot i que en setmanes consecutives, diferenciant el seu nom oficial, per exemple Western & Southern Financial Group Masters en categoria masculina i Western & Southern Financial Group Women's Open en categoria femenina pel seu patrocinador Western & Southern Financial Group. A partir de l'any 2011 es van disputar conjuntament ambdues sota el nom oficial Western & Southern Open.
El torneig va iniciar-se en categoria masculina el 1899 sota el nom de Tri-State Tennis Tournament, incorporant-se la categoria femenina l'any següent. Aquesta, però, va deixar de disputar-se el 1974 per reprendre's el 2004. Inicialment el torneig va disputar-se sobre gespa per canviar de superfície diverses vegades, passant per la terra batuda, fins a instaurar definitivament la pista dura actual i celebrant-se durant el mes d'agost com a torneig de preparació del US Open, formant part posteriorment de la US Open Series.
L'edició de 2020 es va disputar a les instal·lacions on se celebraria el US Open a continuació, al USTA Billie Jean King National Tennis Center de Nova York, a causa de la pandèmia per coronavirus i amb la intenció d'evitar viatges innecessaris dels jugadors entre torneigs.
