Meaning
Brazilian Portuguese name from the Spanish surname Murillo, "little wall"
The story
Murilo came into Brazilian Portuguese as a given name from the Spanish surname Murillo, interpreted as “little wall.” The surname has a substantial artistic association in Bartolomé Esteban Murillo, a painter in seventeenth-century Seville. He used his mother’s second surname. His major religious commissions included paintings for Franciscan monks.
Brazilian poet Murilo Mendes was born in Juiz de Fora in 1901. He later said that seeing Halley’s Comet as a child awakened him to poetry. He experimented with new forms of poetry and brought religion, painting and music into his writing. His circle also explored surrealism, bringing unexpected imaginative associations into art.
Mendes later received the international Etna-Taormina poetry prize after nomination for a bilingual anthology. He said that he contacted Brazil’s embassy in Rome and considered the honor Brazil’s.
The 2022 Brazilian census counted 200,096 residents with the first name Murilo, with a median age of 12. The count covers people alive and living in Brazil at the census.

Not on the record in Mexico City, Puerto Rico, England and Wales, Canada, Ireland, New Zealand, Scotland and Poland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown. Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on the South Australia record for 1944 to 2017: that registry withholds nothing, so this spelling was not given there in those years. Not on the Austria record for 1984 to 2025: Statistik Austria publishes every first name down to a single birth, so this name was not given there in those years (before 2010 the record covers babies with Austrian citizenship only). Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
