Luso-Asians (Portuguese: luso-asiáticos) are people whose ethnicity is partially or wholly Portuguese and ancestrally are based in or hail primarily from Portugal, South Asia, Southeast Asia, and East Asia. They historically came under the cultural and multi-ethnic sway of the Portuguese Empire in the East and retain certain aspects of the Portuguese language, Roman Catholic faith, and Latin cultural practices, including internal and external architecture, art, and cuisine that reflect this contact. The term Luso comes from the Roman empire's province of Lusitania, it roughly corresponds to modern Portugal.
