Miss Grand Thailand (Thai: มิสแกรนด์ไทยแลนด์) is an annual Thai beauty pageant that began in 2013 to select a representative for Miss Grand International. The pageant has been owned by Nawat Itsaragrisil since its inception and was originally broadcast on Channel 7 from 2013 – 2019. In 2020 it moved to One 31, then only on the social media livestream since 2022.
In the first three editions of the contest, the national entrants were selected by the organization directly. In 2016, the license was distributed to the provincial organizers, and since then the pageant has contestants chosen by the seventy-seven provincial licensees through their regional competitions. Since 2017, all seventy-seven provincial representatives must be determined by provincial contests; the national organizer has not allowed the provincial licensees to appoint their representatives to compete on the national stage, unless with the organization's consent.
The reigning Miss Grand Thailand is Pattama Jitsawat of Chonburi who was crowned on 28 March 2026 at the MGI Hall, Bravo BKK Mall in Bangkok. She will represent the country at the Miss Grand International 2026 pageant.
