Miss Grand Ubon Ratchathani

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.^[9] The license for Ubon Ratchathani province was granted to a local entrepreneur, Nontat Nithipanich,^[5] who organized the first Miss Grand Ubon Ratchathani contest in that year on 8 May and named a model from Warin Chamrap, Chanita Chantanet, the winner.^[2] Nithipanich relinquished the franchised to a producer from Sisaket province, Awirut Akkabut [th], in 2020.^[10]

The pageant was sometimes co-organized with other Miss Grand Thailand's provincial stages; in 2020 with Miss Grand Sisaket^[10] and 2025 with Miss Grand Phetchabun.^[11][12] Due to the cancellation of the 2021 national event,^[13] the 2021 Miss Grand Ubon Ratchathani winner was sent to compete in the 2022 national pageant instead, resulting in the skip of the 2022 provincial pageant.^[14]
