2025 Korean Mixed Doubles Curling Championship

The 2025 Korean Mixed Doubles Curling Championship, South Korea's national mixed doubles curling championship, was held from July 21 to 29 at the Jincheon National Training Centre in Jincheon, South Korea. The winning pair of Kim Seon-yeong and Jeong Yeong-seok became the Korean National Team for the 2025–26 curling season. They will represent Korea at the 2026 World Mixed Doubles Curling Championship in Geneva, Switzerland and the Olympic Qualification Event to try to qualify for the 2026 Winter Olympics. Through regional qualifiers, the field was narrowed down from over fifty teams to twenty-five who competed in the national championship. The preliminary round was held in a round robin format which qualified the top two teams in each pool and the two best third place teams for the playoff round. In a continuation of the 2024 format, players from different regions were able to compete together, forming composite teams.

Defending champions Kim Kyeong-ae and Seong Ji-hoon earned an automatic bye to the championship and did not have to compete in the regional qualifiers. 2024 runner-up Lee Ki-bok returned with new partner and 2025 world junior champion skip Kang Bo-bae while bronze medalists and 2023 silver medalists Kim Hye-rin and Yoo Min-hyeon again qualified out of Gangwon. 2025 national women's champions Kim Min-ji and Seol Ye-ji both qualified out of Gyeonggi with their partners Jeong Byeong-jin and Kim San respectively, while four of five members of Kim Soo-hyuk's men's championship rink also advanced to the championship with members of Ha Seung-youn's squad. Additionally, Gangneung's Kim Eun-jung competed in mixed doubles for the first time with partner Park Jong-duk, though the pair did not advance to the finals.
