The surname Orduna originated in the Basque region of Spain and France. It is derived from the Basque word "urduna," meaning "fertile valley" or "fertile land." The name likely originated as a topographic surname, referring to someone who lived in or near a lush valley or fertile area.
One of the earliest known references to the Orduna surname can be found in the Cartulario de San Millán de la Cogolla, a collection of medieval documents from the monastery of San Millán de la Cogolla in La Rioja, Spain. This cartulary, dating back to the 11th century, mentions individuals with the surname Orduna living in the region.
In the 13th century, the Orduna surname appeared in the Becerro Galicano, a census-like document that recorded names and properties in Galicia, Spain. This document provides evidence of the surname's presence in northwestern Spain during the Middle Ages.
One notable individual with the Orduna surname was Juan de Orduna, a Spanish explorer who accompanied Christopher Columbus on his second voyage to the Americas in 1493. Juan de Orduna was born in the late 15th century in Spain and played a role in the early exploration and settlement of the Caribbean islands.
Another historical figure was Martín de Orduna, a 16th-century Spanish architect and sculptor. He was responsible for the design and construction of several notable buildings in Seville, including the Hospital de las Cinco Llagas (Hospital of the Five Holy Wounds), completed in 1571.
In the 17th century, Diego de Orduna was a Spanish painter known for his religious works. He was born in Madrid in 1620 and is credited with painting several altarpieces and murals in churches throughout Spain.
During the 18th century, José de Orduna y Villaquirán was a prominent Spanish naval officer and explorer. Born in Bilbao in 1720, he served in the Spanish Navy and participated in various expeditions to the Americas and the Pacific Ocean.

Demographics
Among Census respondents with the surname Orduna, the largest self-reported group is Hispanic at 90.7%. The next largest groups are White (3.6%) and Asian/Pacific Islander (2.5%).
The bar chart below shows how Orduna bearers described their own race and ethnicity on the 2020 Census form. 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.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Orduna surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Orduna (2000, 2010, 2020).
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
