The flag of Sint Maarten consists of a white triangle situated at the hoist charged with the constituent country's coat of arms, along with two horizontal bands of cherry red and navy blue.

Adopted in 1985 shortly after the territory was granted a coat of arms, it has been the flag of Sint Maarten since 13 June of that year.

[6] Sint Maarten was accorded its own distinct coat of arms in November 1982,[7] and subsequently held a contest in August of the following year to design a separate flag.

[7] The shield depicts a garland of yellow sage – the official flower of the territory – as well as the Constitutional Court of Sint Maarten in Philipsburg and (top right) the Dutch–French friendship monument delineating the boundary between the Dutch and French sections of the island.

[7][9] The crest consists of a pelican in front of a yellow sun, while the motto in Latin on a ribbon scroll under the escutcheon – Semper progrediens – means 'always progressing'.
