The 2025 World Lacrosse Men's U20 Championship was the tenth edition of the international junior men's field lacrosse tournament for national teams organized by the Federation of International Lacrosse (FIL) held in Seogwipo on Jeju Island, South Korea from August 15 to 24. Due to the challenges in obtaining travel visas, Ghana has been withdrawn but the pool play matches will be recorded as forfeit wins for the opposing teams, and modifications have been made to the placement schedule to account for the change.
