Myeik (Burmese: မြိတ်; MLCTS: mrit, pronounced [mjeɪʔ] or [beɪʔ]; Mon: ဗိက်, [pòik]; Thai: มะริด, RTGS: Marit, [má(ʔ).rít]; formerly Mergui, /mɜːrˈɡwiː/) is a rural city in Tanintharyi Region, Myanmar, located in the extreme south of the country on the coast off an island on the Andaman Sea.

From the 16th century on, the city was an important seaport and trading center with the Europeans, who would land at Mergui, travel upriver to Tenasserim and then cross the mountains to reach Ayutthaya.

The French officer Chevalier de Beauregard was made Governor of the city of Myeik after the Anglo-Siamese War (1687) that resulted in the English being expelled from Siam.

[3] De Beauregard was named Governor by Narai, the king of the Ayutthaya Kingdom, replacing an Englishman, Samuel White.

[9] The population is primarily engaged in resource extraction industries like fishing, the production of natural rubber and coconuts, the collection of edible bird's nests, and pearl farming.
