The 2022 Korea Open (also known for sponsorship purposes as the 2022 Eugene Korea Open Tennis Championships for the men's tournament and the 2022 Hana Bank Korea Open for the women's tournament) was a combined ATP Tour and WTA Tour tennis tournament took place at the Olympic Park Tennis Center in Seoul, South Korea on outdoor hard courts from 19 to 25 September 2022 for the women and from 26 September to 2 October 2022 for the men.[1] [2] It was the 18th edition of the women's tournament, and the first edition of the men's tournament since 1996. The tournament was a WTA 250 event on the 2022 WTA Tour (after being a WTA 125 level tournament in 2021), and a ATP Tour 250 event on the 2022 ATP Tour after several tournaments in China were cancelled because of the ongoing COVID-19 pandemic.
