Luso-Asians (Portuguese: Luso-Asiáticos) are those people by ethnicity based primarily in Asia who come under the cultural and multi-ethnic sway of the Portuguese Empire and retain aspects of the Portuguese language, Roman Catholic faith, and cultural practices, including internal and external architecture of Houses, art, and cuisine that reflect this contact. "Luso" is from the Roman province Lusitania which is roughly the ancestor of the modern state of Portugal in the Iberian Peninsula.
