Bayingyi people (Burmese: ဘရင်ဂျီ) also known as Luso-Burmese, are a subgroup ethnicity of Luso-Asians, and are the descendants of Portuguese mercenaries or adventurers who came to Myanmar (Burma) in the 16th and 17th centuries.

By the mid-17th century, the mercenaries, who had proven politically dangerous as well as expensive, had virtually disappeared in favour of cannoneers and matchlockmen in the Burmese military ahmudan system.

In 1599, de Brito was made governor of Syriam, a busy port on the Bago River in what is now Yangon’s Thanlyin Township, where the ruins of the country’s first Catholic church can be seen on a hilltop.

Now the descendants of these Portuguese, heavily integrated both ethnically and culturally into the Bamar, live scattered across an unknown range of villages and towns in this region known as 'Anya'.

[9] Centuries of inter-marriage have left the Bayingyi more or less assimilated into the Bamar ethnic group of Myanmar, but they have still kept their sense of Portuguese identity and Roman Catholic religion, and in some individuals obvious European phenotypes are still present.
