Miss Grand Surat Thani (Thai: มิสแกรนด์สุราษฎร์ธานี) is a Thai provincial beauty pageant which selects a representative from Surat Thani province for the Miss Grand Thailand national competition,[1][2][3][4] founded in 2016 by a local talent manager, Teeraphat Phungsiri.

[1] Surat Thani's representatives have never won the main title since the first competition in the Miss Grand Thailand pageant in 2016.

[5][6] 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 Miss Grand Thailand 2014 [th] and 2015 [th] finalist, Natthakorn Kaew-Anan, was elected the winner.
