The Zhengzhou Open was a tournament for professional female tennis players played on outdoor hardcourts. The event was held in Zhengzhou, China, since 2014 as an ITF and then as a WTA 125 tournament in 2017 and 2018. Subsequently it was upgraded and from 2019 onward was classified as a WTA Premier level tournament, replacing the Connecticut Open in the United States. After a three-year hiatus, the tournament returned in 2023 for one year as a WTA 500 event.
