Origin
Meaning and origin of Kirilov
The surname KIRILOV is of Russian origin, originating from the early 16th century. It is a patronymic name, derived from the given name Kirill, which itself comes from the Greek name Kyrillos, meaning "lordly" or "masterful". The name is found primarily in areas of modern-day Russia, Belarus, and Ukraine.
One of the earliest recorded instances of the name KIRILOV can be found in the Veliky Novgorod Chronicles, a collection of historical manuscripts dating back to the 12th century. These chronicles mention a boyar (nobleman) named Kirill Ivanovich KIRILOV who served under the reign of Ivan the Terrible in the mid-16th century.
The name KIRILOV is also linked to several notable figures throughout Russian history. One prominent example is Vasily Vasilievich KIRILOV (1706-1778), a Russian statesman and diplomat who served as the governor of Smolensk and was later appointed as the first Russian ambassador to the Kingdom of Prussia.
Another notable KIRILOV was Ivan Kirilovich KIRILOV (1689-1737), a Russian mathematician and astronomer who made significant contributions to the development of the Julian calendar reform. His work was instrumental in the transition from the Julian to the Gregorian calendar in Russia.
In the 19th century, Grigory Ivanovich KIRILOV (1835-1888) was a renowned Russian mining engineer and geologist. He made significant discoveries in the Ural Mountains and was instrumental in the establishment of several mining settlements in the region.
During the Soviet era, Yuri Vasilievich KIRILOV (1920-1998) was a prominent Soviet military commander who served as the Chief of the General Staff of the Soviet Armed Forces from 1983 to 1988. He played a crucial role in the restructuring of the Soviet military during the latter years of the Cold War.
While the name KIRILOV has its roots in Russia and the Slavic regions, it has also been adopted and adapted in various forms in other countries, particularly those with significant Russian diaspora communities.

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 Kirilov surname at the time of the 2020 Census, not any inherent property of the name itself.
