The story of Rio

Rio is the Spanish and Portuguese word for river, and in English it also calls up Rio de Janeiro. As a first name it is used for both boys and girls, and there is no single origin story. In Japan, Rio is a separate name written with Japanese characters.

The best-known Rio in these islands is the English footballer Rio Ferdinand, and many other footballers carry the name.

In Ireland Rio first reached three babies a year in 2002, and it has been given mostly to boys. Its biggest year was 2020, with 19 boys, and it matched that in 2025, when it reached number 239, its best rank so far. It is more popular in Northern Ireland, where 18 boys were named Rio in 2025.
