Meaning & origin

Rosalio is a rare masculine name with Spanish and Italian roots, deriving from the Latin 'rosa' meaning 'rose'. First recorded in the U.S. in 1911, the name saw its peak popularity in 1928, when it was most commonly used among Hispanic families. After declining for decades, it has been slowly rising in use since 2019, currently holding a rank of 7,194 in 2025, with an occurrence rate of 1 in 155,280. While no top states appear in the data, Rosalio's revival suggests a renewed interest in vintage Hispanic names, and it remains a distinctive choice with a timeless floral meaning.

Rosalio is a Spanish and Italian form of the Latin name Rosalius, which is derived from rosa, meaning 'rose'. The name has been used in the Spanish-speaking world and Italy since the Middle Ages, often in reference to the Virgin Mary as 'Rosa Mystica' or in honor of Saint Rosalia, the patron saint of Palermo. It saw periodic use in the United States among Hispanic communities in the early 20th century.
