Meaning & origin

Roi is a concise and cross-cultural name with two plausible meanings: 'king' in Spanish and 'my shepherd' in Hebrew. Its simplicity and familiar sound, akin to Roy, make it accessible yet distinctive. First recorded in U.S. data in 1952, Roi has experienced a steady rise in use since 1999, reaching its peak rank of 3379 in 2025. With a rate of 1 in 50,238 births that year, it remains a rare choice, appealing to parents seeking a name with royal or pastoral resonance without the popularity of similar names like Roy or Rey.

Roi has two likely origins. It may be from Spanish 'rey' (king), used as a given name in Spanish-speaking countries, or from Hebrew 'Ro'i' (my shepherd), a name with pastoral significance. As a Spanish name, it parallels the English name 'Roy' and shares its royal connotation. The Hebrew origin is found in Jewish communities. The name has seen modest use in the United States since the mid-20th century, with a recent uptick in popularity.
