Isleños are the descendants of Canarian settlers and immigrants to present-day Louisiana, Puerto Rico, Texas, Cuba, the Dominican Republic, Venezuela, and other parts of the Americas. In these places, the name isleño was applied to the Canary Islanders to distinguish them from Spanish mainlanders known as "peninsulars". Formerly used for the general category of people, it now refers to the specific cultural identity of Canary Islanders or their descendants throughout Latin America and in Louisiana, where they are still called isleños. Another name for Canary Islander in English is "Canarian." In Spanish, an alternative is canario or isleño canario.

Canary Islanders, or Canarians, are the people of the Canary Islands, an autonomous community of Spain near the coast of northwest Africa. The distinctive variety of the Spanish language spoken in the region is known as habla canaria or the (dialecto) canario. The Canarians, and their descendants, played a major role during the conquest, colonization, and eventual independence movements of various countries in Latin America. Their ethnic and cultural presence is most palpable in the countries of Uruguay, Venezuela, Cuba and the Dominican Republic as well as the U.S. territory of Puerto Rico.
