</div> Miss Grand Surat Thani () is a Thai provincial beauty pageant which selects a representative from Surat Thani province for the Miss Grand Thailand national competition, founded in 2016 by a local talent manager, Teeraphat Phungsiri.
Surat Thani's representatives have never won the main title since the first competition in the Miss Grand Thailand pageant in 2016. Its representatives were placed among the semi-finalists (Top 10/12) twice; in 2018 and 2019.
In 2016, after Miss Grand Thailand began franchising the provincial competitions to individual organizers, who would name seventy-seven provincial titleholders to compete in the national pageant, the license for Surat Thani province was purchased by a local entrepreneur, Teeraphat Phungsiri, who organized the first contest of Miss Grand Surat Thani on 14 May 2016, in which a former and finalist, Natthakorn Kaew-Anan, was elected the winner.
The pageant was skipped once; in 2021, due to the COVID-19 pandemic in Thailand, the national organizer was unable to organize the national event, and the country representative for the international tournament was appointed instead.
The following table details Miss Grand Surat Thani's annual editions since 2016.
