Isleños are a Spanish ethnic group living in the state of Louisiana in the United States, consisting of people primarily from the Canary Islands. Isleños are descendants of colonists who settled in Spanish Louisiana between 1778 and 1783 and intermarried with other communities such as French, Acadians, Creoles, Hispanic Americans, Filipinos, and other groups, mainly through the nineteenth and early twentieth centuries.

Louisiana Creoles are a Louisiana French ethnic group descended from the inhabitants of colonial Louisiana before it became a part of the United States during the period of both French and Spanish rule. They share cultural ties such as the traditional use of the French, Spanish, and Creole languages and predominant practice of Catholicism.
