Apart from the veterans, four more Thai athletes also topped the roster lineup to make their third Olympic appearance, namely welterweight boxer Sailom Adi, freestyle swimmer Natthanan Junkrajang, pistol shooter Tanyaporn Prucksakorn, and world's top-ranked skeet shooter Sutiya Jiewchaloemmit. Other notable Thai athletes included professional golfer Ariya Jutanugarn, who became the first for her country to capture the major championship title, and world's top four badminton player Ratchanok Intanon, who was named as the country's historic first female flag bearer in the opening ceremony.
Thailand left Rio de Janeiro with a total of six medals, being considered its most successful Olympics since 2004. Four of these medals were awarded to the team in weightlifting, including two golds won by Sopita Tanasan and Sukanya Srisurat, and two others in taekwondo. For the first time in four decades, Thailand failed to pick up a single medal in boxing, as neither of its fighters progressed beyond the quarterfinal round.
