The Korea Open (Korean: 코리아오픈테니스대회) is a professional tennis tennis tournament held in Seoul, South Korea. The women's edition started in 2004 as a WTA International tournament and was played at the Seoul Olympic Park Tennis Center on outdoor hardcourts. In 2012 and 2013, it was sponsored by Korea Development Bank (formerly sponsored by Hansol).[1] In 2014, Kia Motors was the sponsor.
In 2020, the tournament was cancelled due to the COVID-19 pandemic. In 2021, it was originally scheduled as a WTA 250 event in September, but was later postponed and rescheduled to December as a WTA 125 tournament and indoor event.[2]
In 2022, the women's edition returned as a WTA 250 tournament and the sole edition of the men's ATP World Tour 250 event also took place.[3] The women's event would continue and in 2024 would be upgraded to a WTA 500 event.
