The name is likely derived from the given name Zanardo, a regional variation or diminutive of the name Bernardo, which itself originates from the Germanic elements "bern" meaning bear and "hard" meaning brave or strong.

Another significant individual is Giovanni Zanardelli, a 17th-century artisan known for his intricate woodwork and sculptures, often commissioned for churches in the Lombardy region. His work exemplified the Baroque style and contributed to the cultural heritage of the area.
Historical manuscripts, such as municipal archives, provide evidence of Antonio Zanardelli, a merchant active in the 14th century. His trade in textiles and spices opened routes between Lombardy and other parts of Europe, showcasing the economic significance of the Zanardelli family in regional trade networks.
Vittorio Zanardelli, born in 1880 and died in 1956, was a renowned architect who played a pivotal role in the architectural renaissance of Italian towns in the early 20th century. His design philosophy merged traditional Italian craftsmanship with modernist aesthetics, leaving a lasting impact on urban development.

The bar chart below shows how Zanardelli 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 Zanardelli surname at the time of the 2020 Census, not any inherent property of the name itself.
