Fatima Bosch Fernandez of Mexico was crowned Miss Universe 2025 on November 21 at Impact Challenger Hall, Pak Kret, Nonthaburi, Thailand, competing against 120 candidates. She became the fourth Mexican woman to earn the Miss Universe title, after Lupita Jones, Ximena Navarrete, and Andrea Meza.

The pageant was marked by controversy when Thailand's national director Nawat Itsaragrisil reprimanded Bosch during a sash ceremony on November 4, leading several contestants to walk out. Despite this, Bosch emerged as a fan favorite and eventual winner. Miss Thailand Praveenar Singh was first runner-up, and Miss Venezuela Stephany Abasali was third.
