The 2023 J1 League, also known as the 2023 Meiji Yasuda J1 League (Japanese: 2023 明治安田生命J1リーグ, Hepburn: 2023 Meiji Yasuda Seimei J1 Rīgu) for sponsorship reasons, was the 31st season of the J1 League, the top Japanese professional league for association football clubs, since its establishment in 1992. This was the ninth season of J1 League after being renamed from J. League Division 1.
