Suchata Chuangsri (Thai: สุชาตา ช่วงศรี; born 20 September 2003) also known by the Thai nickname Opal (Thai: โอปอล) is a Thai model and beauty queen who was crowned Miss World 2025. She is the first Thai woman ever to win Miss World.

Suchata was born on 20 September 2003 in Phuket province to parents Thanet Donkamnerd and Supatra Chuangsri.

Prior to becoming Miss Universe Thailand, Suchata was pursuing a bachelor's degree in politics and international relations at the Faculty of Political Science of Thammasat University.

When Suchata was 16 years old, a 10-centimeter tumor was found in each of her breasts, and she underwent successful surgery to remove the tumors. Her experience led Suchata to become an advocate for breast cancer awareness, and she began competing in pageantry in order to bring awareness to the topic.

In 2022, at the age of 18, Suchata entered the Miss Universe Thailand 2022 competition and finished as the third runner-up. She was later promoted to second runner-up following the resignation of the original first runner-up, Nicolene Limsnukan.

In 2024, Suchata was appointed to represent Bangkok in the Miss Universe Thailand 2024 pageant. She won several special awards, including Miss Charming Talent and Miss Beauty and Confidence. At the end of the competition, she was crowned Miss Universe Thailand 2024.

Suchata represented Thailand at Miss Universe 2024, held on 17 November 2024 in Mexico City. She placed as the third runner-up and received the Voice for Change silver award.

However, on 22 April 2025, following her appointment as Thailand's representative to Miss World, the Miss Universe Organization announced her removal from the third runner-up position for not completing her 12-month reign before accepting another title.
