The national finalists for Miss Grand Thailand 2023 were chosen through the provincial pageants held by the different provincial licensees, who in some cases are responsible for more than one province, e.g., Piriya Siannok, who holds the licenses for Amnat Charoen, Chai Nat, Chumphon, Nan, Nong Bua Lamphu, Prachinburi, and Trang.

[10][11][12] Of all participating candidates, the representative of Chonburi province, Ratrapee Thamjalkul, was appointed as the replacement for the original winner, Kritsadaporn Nakrai, who was dethroned by the provincial licensee for not being able to fulfill the duties.

The audition and pre-final rounds were held at the Hotel Swissôtel Bangkok Ratchada, in which the panel of judges selected the finalists based on their Mor Lam-related performances.

Meanwhile, the final round of the contest will be later held with the full show of Rabieb Wathasilp Mor Lam Band on April 25 at the MGI Hall in Huai Khwang.
