Cyclist Jai Angsuthasawit, taekwondo fighter Panipak Wongpattanakit and golfer Ariya Jutanugarn won the major awards from the Sport Writers Association of Thailand on Saturday.
Jai and Panipak were named the male and female amateur athletes of the year respectively, while Ariya received the best professional athlete award.
Jai and Ariya were not present at Saturday's ceremony at the Arnoma Grand Bangkok as they are competing overseas.
Jai became the country's first ever Asian Games gold medallist in track cycling after a photo-finish in the keirin event last year.
Panipak, the world's top taekwondo exponent in the 49kg division, also won gold at the 2018 Asian Games. She was also a winner at the 2019 world championships.
Panipak, 21, is considered one of Thailand's best hopes at the 2020 Olympics although she still has to qualify for the Tokyo Games.
After receiving the trophy yesterday, Panipak thanked parties concerned for giving "a country's girl" the chance to become a sporting star.
"I will do my best [to win gold] at the Olympics," said Panipak, who won bronze at the 2016 Olympics.
National taekwondo coach Choi Young-Seok was named the coach of the year, while the Taekwondo Association of Thailand got the best association award.
Ariya, 23, won three LPGA tournaments last year, including the US Women's Open for her second major crown.
She became the first player to sweep all LPGA major awards of the season, including the player of the year, Race to the CME Globe that comes with a US$1 million bonus, money title, and Vare Trophy for the lowest scoring average.
