HTMS Sukhothai (FS-442) (Thai: เรือหลวงสุโขทัย, RTGS: Ruea Luang Sukhothai) was a corvette of the Ratanakosin class operated by the Royal Thai Navy that was launched in 1986.

On 18 December 2022 in the Gulf of Thailand, high winds and strong waves caused seawater to flow into the warship; this flooding caused the engines to fail, and the pumps also became unusable. Sukhothai continued to take on water until eventually sinking overnight. As of 2 March 2023^[update], the Royal Thai Navy had rescued 76 sailors and found 24 dead. An additional five sailors are presumed dead but their bodies were not found.
