Rio
REE-oh
Rio comes from the Spanish and Portuguese río / rio meaning “river.” It entered English primarily as a geographic reference—most famously through Rio de Janeiro in Brazil.
As a given name, Rio has been used in Spanish-speaking countries for decades. Its adoption in English-speaking contexts accelerated with the 2011 animated film Rio and the more general trend toward short, nature-inspired names.
Rio is at its all-time US peak: No. 516 in 2024 with 591 births. The name has never ranked higher in SSA records.
What the name Rio means
The Duran Duran song “Rio” (1982) introduced the name to a generation of English speakers. The Brazilian city, the animated film, and the song all contribute to the name’s vivid geographic and cultural associations.
One syllable in quick English speech—REE-oh—though technically 2 syllables. The open vowels make it bright and easy to say, with a quality shared by names like Leo, Theo, and Milo.
Rio works as both a standalone name and a short form of longer names like Mario or Rio’s parent name constructions. Its brevity and clarity make it versatile.
The name is genuinely gender-neutral in English usage, appearing in SSA records for both boys and girls. In Spanish-speaking contexts it leans male.
