Núñez
A Spanish surname meaning “son of Nuño,” from an old personal name probably linked to a Latin nickname for “grandfather” or “elder.”
The #242 most common surname in the United States (2010 Census) — about 1 in every 2,463 Americans shares it.
Etymology
Núñez is a Spanish patronymic surname, formed with the old possessive ending -ez meaning “son of.” It comes from the personal name Nuño, an ancient Iberian name of uncertain deeper origin. Many scholars connect Nuño with Latin nunnus/nonnus, words used for “grandfather,” “uncle,” or as terms of respect for an older man, though the exact path is not fully certain.
History
The surname is long established in Spain and is especially common in Spanish-speaking regions with strong historical Iberian naming traditions. The cited 19th-century source lists Núñez among medieval-style surnames already documented in Tarragona in 633, reflecting how old the name was thought to be in Spain. It later spread widely through the Spanish Empire and remains common across Latin America.

Fun fact
The tilde in Núñez marks the ñ sound, so the name is pronounced with a “ny” sound, not a plain “n.”
