Şu anda San Diego Açık olarak bilinen Güney Kaliforniya Açık, San Diego, California'daki Barnes Tenis Merkezi'nde düzenlenen bir ATP 250 ve WTA 500 turnuvasıdır. Etkinlik, 1887'den 1978'e kadar süren Güney Kaliforniya Şampiyonası olarak ortaya çıktı. Ağustos 2021'de, Asya Swing'in COVID-19 salgını nedeniyle iptal edilmesinden sonra, Barnes Tennis Center San Diego'ya iki yıllık 250 turnuva lisansı verildi. Bundan önce, en son 2015 yılında Carlsbad'da bir WTA Challenger olarak düzenlenen bir WTA etkinliğiydi.
