What Does the Name Rui Mean?

Rui is a Portuguese masculine name meaning "renowned ruler." It comes from a Germanic name reconstructed as Hrōþirīks, formed from hrōþi- ("fame, glory") and rīks ("ruler, king"). The same Germanic source produced Spanish Rodrigo, English Roderick, and German Rüdiger. In Portuguese, Rui is usually connected with Rodrigo - often described as a shortened form that became a name in its own right - and the two names trace back to the same older name.

Rui is also a romanization of Chinese given names, most often from 瑞 ruì, "auspicious omen," or 睿 ruì, "wise, perspicacious." These names are unrelated to the Portuguese one; they resemble it only when written in the Latin alphabet.

Rui Name History & Origins

The Germanic name behind Rui reached the Iberian Peninsula with the Visigoths, whose kingdom covered most of the peninsula from the fifth to the eighth century. Its Latinized form, Rodericus, appears in medieval Iberian records, and from it came both Rodrigo and the shorter Portuguese Rui. Medieval Portuguese texts also use the spelling Ruy; both forms circulated for centuries before Rui became the usual modern spelling.

Rui has long been a common given name in Portugal and Brazil. Bearers include the chronicler Rui de Pina, the Brazilian statesman and writer Rui Barbosa, and the Portuguese footballer Rui Costa.

In Chinese, ruì is used as one element of a two-character given name, and Rui is simply the pinyin spelling of that syllable. In Japanese, Rui is likewise a romanization, applied to given names written with various kanji, such as 塁; those names have their own separate origins and meanings.
