The Mixed doubles tournament at the 2023 BWF World Junior Championships will be held at The Podium, Spokane, United States from 2 to 8 October 2023.[1] Zhu Yijun and Liu Shengshu of China were the gold medalists in the previous edition, but were unable to defend their title as a pair as Liu had moved into the senior age category. Zhu this time partnered with her opponent in the 2022 final, Huang Kexin, and made it to the final. Despite being just one point away from victory, Zhu and Huang had to give up the gold medal to their compatriots, Liao Pinyi and Zhang Jiahan.[2] Zhu also failed to repeat the achievement of two world junior championship titles obtained in the previous edition. Bronze medals were won by Low Han Chen and Chong Jie Yu from Malaysia and Jonathan Farrell Gosal and Priskila Venus Elsadai from Indonesia.[3]
The seeds are determined based on the world rankings released on 19 September 2023.[4]
