Origin
Meaning and origin of Agusti
The surname Agusti has its origins in the Catalan region of Spain, dating back to the 12th century. It is derived from the Catalan personal name "Agustí," which is a variant of the Latin name "Augustinus," meaning "venerable" or "worthy of respect."
Agusti is believed to have first appeared in the Catalan town of Tarrasa, now known as Terrassa, located near Barcelona. The name may have been adopted by families residing in or near this town, as it was a common practice for surnames to be derived from place names during this period.
One of the earliest recorded instances of the Agusti surname can be found in the "Llibre del Repartiment," a historical document from the 13th century that recorded the distribution of lands and properties in the Kingdom of Valencia after the Christian conquest. This document mentions several individuals with the surname Agusti, suggesting that the name was already well-established in the region by that time.
In the 14th century, a notable figure bearing the Agusti surname was Miquel Agusti, a Catalan poet and writer born in Valencia in 1380. His poetic works, including "Lo Llibre de les Dones," were highly regarded during the Renaissance period.
The 15th century saw the rise of the Agusti family in Mallorca, an island in the Balearic archipelago. One notable member of this family was Jaume Agusti, a merchant and landowner who played a significant role in the economic and political affairs of the island in the late 1400s.
During the 16th century, the Agusti surname gained prominence in the city of Barcelona. In 1532, a man named Joan Agusti was appointed as the first "Mestrescola" (Master of Studies) at the Cathedral of Barcelona, a position of great importance in the education and religious life of the city.
In the 17th century, the Agusti family produced several notable figures in the arts and sciences. One such individual was Miquel Agusti, born in 1633, who was a renowned painter and sculptor in Barcelona. His works can be found in various churches and museums throughout Catalonia.
As the Agusti surname spread across Spain and beyond, it underwent various spelling variations, such as Agustí, Agustín, and Agosti, reflecting regional linguistic differences. However, the core meaning and origin of the name remained rooted in the Catalan region and its connection to the Latin name Augustinus.

The bar chart below shows how Agusti bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Agusti surname at the time of the 2020 Census, not any inherent property of the name itself.
