Uzbekistan's only gold medallist at the International Chemistry Olympiad — won at home 58th IChO, Tashkent • 27th in the world • all four Uzbek entrants medalled

Uzbekistan hosted the 58th International Chemistry Olympiad in Tashkent from 10 to 19 July 2026, with students from more than 90 countries competing across two long examination days. Of the host nation's four entrants, all four medalled — and the single gold went to Rayhona Tuymuradova, who finished 27th in the world, the highest placing in the Uzbek delegation.

Biography

Rayhona Tuymuradova is an Uzbek secondary-school chemistry student who won a gold medal at the 58th International Chemistry Olympiad, held in her own country's capital, Tashkent, from 10 to 19 July 2026.

She finished 27th in the individual standings, the best result of any member of Uzbekistan's four-person delegation and the team's only gold. Her team-mates Mirjalol Homidjonov, Azizmuhammad Hafizov and Jasur Mustafoev each took silver, meaning every Uzbek competitor came away from the home Olympiad with a medal.

The 2026 competition awarded 41 gold, 74 silver and 112 bronze medals in total. The IChO tests students across a theoretical paper and a laboratory practical, both taken over five hours, and restricts entry to secondary-school students under 20.

Uzbekistan's all-time record in the official IChO results database stands at 9 gold, 18 silver, 21 bronze and 1 honourable mention. Hers is the country's most recent gold.

Her name appears in several transliterations: Rayhona Tuymuradova in the IChO database's English column, Rayhona Tuymurodova in the original-script column, and Raykhona Tuymurodova in some Uzbek press coverage. Her age and date of birth have not been published.

Why This Matters

Rayhona Tuymuradova matters because host nations rarely peak at their own Olympiad — the organisational burden usually falls on the same institutions that train the team. Uzbekistan medalled with all four entrants and took a gold anyway, and the gold was hers. In a database that records only nine Uzbek golds in the country's entire IChO history, that is a scarce result.
