Ibarra
A Basque surname meaning “the valley” or “the plain by the riverbank,” originally from a place-name.
The #507 most common surname in the United States (2010 Census) — about 1 in every 4,674 Americans shares it.
Etymology
Ibarra is a Basque surname taken from a place-name built on the Basque word ibar, meaning “valley” or “meadow by a river,” with the definite article -a, “the.” So the name likely began as a label for someone who lived at or came from “the valley” or “the river meadow.” In surnames, it is common across the Basque Country and northern Spain.
History
The name is strongly associated with the Basque region and appears in many compound and related Basque surnames. Historical records from Spain and colonial-era genealogies show it in noble and landed families as well as ordinary lineages. It later spread widely through Spain and the Americas, especially through Spanish and Basque migration.

Fun fact
Ibarra is also a common place-name in the Spanish-speaking world, so the surname often points back to a specific locality rather than a single family line.
