Supanida Katethong (Thai: ศุภนิดา เกตุทอง; born 26 October 1997) is a Thai badminton player. She won the gold medal in the women's singles at the 2023 SEA Games, and also part of Thai winning team at the Games in 2021 and 2023. She is nicknamed as May Sai (Thai: เมย์ซ้าย, lit.'left May'), so as to not only avoid confusion with another May, which is Ratchanok "May" Intanon, but to also reference her left-handedness.

Supanida also competed for Thailand at the 2024 Summer Olympics.
