Origin
Meaning and origin of Iriarte
The surname Iriarte is of Basque origin, hailing from the northern regions of Spain and southern France. It is believed to have emerged in the 10th century, derived from the Basque words "Iri" meaning "town" and "arte" meaning "between". The earliest records of the name can be traced back to the Basque Country, specifically in the province of Gipuzkoa.
One of the earliest recorded instances of the surname Iriarte can be found in the Cartulario de San Millán de la Cogolla, a medieval manuscript dating back to the 11th century. This document mentions an individual named Juan Iriarte, who was a landowner in the village of Oñati, located in the heart of the Basque region.
The name gained prominence during the 16th and 17th centuries, with several notable figures bearing the surname Iriarte. Tomás de Iriarte (1750-1791) was a renowned Spanish poet and fabulist, known for his satirical works and contributions to the revival of Spanish literature. His most famous work, "Fábulas Literarias," is a collection of moral tales that became widely popular during his lifetime.
Another prominent figure was Juan de Iriarte (1702-1771), a Spanish naval officer and explorer who played a significant role in the exploration and mapping of the Pacific Coast of North America. He led several expeditions along the western coast, contributing to the expansion of Spanish territories and the advancement of geographical knowledge.
In the 19th century, the Iriarte family produced several influential individuals. Teodoro Iriarte (1832-1898) was a Spanish politician and lawyer who served as a deputy in the Spanish parliament, representing the province of Guipúzcoa. He was known for his advocacy of regional autonomy and the preservation of Basque cultural traditions.
José Iriarte (1824-1891) was a Basque-Argentinian writer and journalist who played a crucial role in the development of Argentine literature. He founded several literary journals and was a prominent figure in the cultural scene of Buenos Aires, promoting the works of local writers and fostering a sense of national identity.
The name Iriarte has also been associated with various place names across the Basque Country and beyond. For instance, the village of Iriarte-Arnábar in the municipality of Lana, in Navarre, bears the name. Additionally, there are several streets and plazas named after notable individuals with the surname Iriarte, commemorating their contributions to their respective communities.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.

Keep in mind that these are self-reported numbers.
