Vietnam's national team finished fifth among 119 countries and territories at the 2026 International Mathematical Olympiad (IMO), securing two gold medals, three silver medals and one bronze medal.
The results were announced by Vietnam's Ministry of Education and Training on the afternoon of July 19.

Each contest day gives contestants 4.5 hours for three problems worth up to 7 points each, for a maximum of 42 across the two papers. Students sit the exam in their own language, with the version registered in advance and approved by the organizers.
Rankings come from the combined two-day score. Under IMO rules medals go to at most half the field, split roughly one gold to two silver to three bronze.
Anyone who misses a medal but scores full marks on a single problem receives an honorable mention. OpenAI is offering ChatGPT Pro subscriptions to this year's gold medalists and to the winner of the Maryam Mirzakhani award.
Vietnam's six students are Pham Dang Nguyen and Ha Manh Hung from Hanoi-Amsterdam High School for the Gifted, Nguyen Hoang Phuong from Phan Boi Chau High School for the Gifted in Nghe An Province, Tran Dai Thanh Danh from the High School for the Gifted, Vietnam National University Ho Chi Minh City, Nguyen Dinh Tung from the High School for Gifted Students in Natural Sciences, Vietnam National University Hanoi, and Nguyen Le Nhat Nam from Hanoi National University of Education High School for the Gifted.
Tung is the only member who has done this before, having taken silver in Australia last year. Nguyen topped the national selection round with a perfect 42 out of 42, and Nam was the highest scorer at this year's national mathematics contest.
With a total score of 168 points, Vietnam ranked behind China (232 points), the United States (207), Russia (196) and Singapore (169). The result marked an improvement from last year, when Vietnam won the same medal tally but finished ninth among 110 participating teams.
The International Mathematical Olympiad, first held in 1959, is the world's most prestigious mathematics competition for secondary school students. Vietnam has participated in the event since 1974.
The 2026 IMO is being held in Shanghai, China, from July 13 to July 21, with contestants competing over two official examination days.
